Abstract:

A novel and simple strategy by introducing a titanate coupling agent into the electrode to improve the supercapacitor performance has been developed in this study. The surface modification of the activated carbon material are conducted under neutral conditions. The improved electrodes are characterized by mechanical tests and electrochemical measurements. The obtained results reveal that the treated activated carbon electrode retains good mechanical properties with decreased bonder content. The electrode prepared using activated carbon treated with the Titanate coupling agent and a bonder mass content of 8.0 % shows the best electrochemical performance. The specific capacitance reaches 376.2 F•g-1, whereas the internal resistance is 0.91 Ω.

Abstract:

A titanate coupling agent, TM-27, was used in surface modification of light-storing pigment to improve its compatibility and stability with the organic system. The surface characteristics of light-storing pigments were reflected by Fourier transform infrared spectroscopy (FT-IR) and scanning electron micrograph (SEM). The result showed that the titanate coupling agent molecular formed a thin layer and binded strongly on the surface of pigments. The modification effect was evaluated on the basis of turbidity and by plotting the afterglow decay curve. The application of light-storing pigment in the printing ink system was also examined. When the dosage of titanate coupling agent was 1.5%, the viscosity of printing ink reached the lowest point. The subsidence rate was reduced from 0.8202 ml/h to 0.5821 ml/h. These results indicated that the modified light-storing pigment had better compatibility and stability with the organic system, and the surface modification did not affect the luminescence properties.

Abstract:

Though there has been a large number of studies concerning the modification of wood plastic composite materials, there is still more to be done. This report aims to study the effect of the coupling agents (PP-g-MAH, silane, titanate) and compatibilizer(SBS) on the mechanical properties of straw flour/waste plastic composites. Straw flour, waste plastic, modifying agents and other additives were mixed evenly in a high speed mixing machine. And the mixed materials were compounded into the pelllets using the twin-screw extruder. Then the test specimens were prepared by the injection molding. The influence of 4% coupling agent (PP-g-MAH, silane, titanate) on the mechanical properties of straw flour/waste plastic composites was researched, and the most suitable coupling agent to the composites was obtained. In order to increase the toughness of the composite materials and to furthermore improve the comprehensive mechanical properties, the WPCs with different contents styrene butadiene styrene (SBS) were investigated. The experimental results showed that the coupling agent PP-g-MAH and the content was 4%, the mechanical properties of the composite materials were better; when SBS content was 5%, the maximum increases of tensile strength, flexural strength and impact strength of SBS modified WPCs were by 14.34%, 20.75%, 34.38% compared to those of neat WPCs respectively.

Abstract:

Mechanical properties of the calcium-plastic composite have a great influence on the containers. The main factors affecting the mechanical properties are the process and material formulations. This paper mainly describes its impact of the addition of coupling agent. Under the usage of analysis of variance on single factor experiment, the mechanical properties of the calcium carbonate-plastic composite with three different coupling agents (silane, titanate and aluminate) were studied in the same test conditions. The results show that: The type and quantity of the coupling agent effect a lot on the mechanical properties of the composite. The silane coupling agent is the most suitable for calcium carbonate-plastic composite packaging materials, and the compatibility of calcium carbonate and polyethylene can be improved. When the silane coupling agent was at a 2.25 wt. % concentration, the tensile and flexural strength were improved obviously, especially the tensile strength increased by 23.24%, but the impact strength improved slightly.

Abstract:

Nano-TiO2 was modified with a titanate coupling agent, LICA38 [neopentyl (dially) oxy, tri (-dioctyl) pyrophosphate titanate]. X-ray photoelectron spectroscopy (XPS) was used to evaluate the surface characteristics of the bare and the modified nano-TiO2. It was demonstrated that the carbon content of the bare TiO2 is 37.9 atm. %, and that of the modified TiO2 is 47.2 atm. %. Moreover, the density of the -C-H (-C-C) and -C-O groups increases due to modification, and the atomic percentage of C=O and -OH groups reduces. These results indicate that the -C-H (-C-C) and -C-O groups from LICA38 have been introduced to the surface of nano-TiO2 by coupling reaction with the hydroxyl groups.

Abstract:

In this paper, stearic acid, titanate coupling agent (NDZ-311) and silane coupling agent (KH-570) were selected as modifiers to modify colemanite powder and the resulted products were characterized by XRD and FT-IR. The results show that the surfaces of colemanite particles were effectively modified by stearic acid and coupling agents. The modified colemanite /EVA composites were then prepared and the effect of coupling agent addition on the mechanical properties and flame retardancy of EVA composites was investigated. The EVA composite doped with 40% of modified colemanite (coupling agent accounting for 1% of colemanite mass) exhibits a tensile strength of 9.80MPa, a breaking elongation of 696.5% and a limit oxygen index of 29.6%. The complex flame retardant was obtained by means of grafting amine polyphosphate onto the surface of colemanite using polyphosphoric acid (PPA) and laurylamine as raw materials. The obtained product was analyzed by XRD and FT-IR. The EVA composite doped with 40% of the complex flame retardant has a tensile strength of 8.57MPa, a breaking elongation of 671.3% and a limit oxygen index of 32.6%.

In order to prepare high activated ground granulated blast furnace slag (GGBFS), tetra-isopropyl titanate was used to process GGBFS in this study. Internal standard method of infrared spectroscopy (FT-IR) was used to study the activation extent of GGBFS influenced by the concentration of tetra-isopropyl titanate, activation temperature and time. The FT-IR analyses showed that the extent of GGBFS coupling reaction was the highest, when the accelerating agent was 0.6%, the concentration of tetra-isopropyl titanate, activation temperature, activation time were 1%, 100°C and 30min, respectively. The GGBFS which is activated by tetra-isopropyl titanate remarkable improves the mechanical properties of artificial marble.

Abstract:

ZnO nanorods and nanoparticles were successfully modified by NDZ-311w titanate coupling agent. The result of lipophilic degree showed that both ZnO nanocrystals with different morphologies were well lipophilic. Although both values of lipophilic degree firstly became larger and then smaller with the increase of modifier dosage, the different maximal lipophilic degree of ZnO nanorods and nanoparticles could be 68.8% and 77.9%, respectively. By comparing the two curves of lipophilic degree of surface modified ZnO nanocrystals with different morphologies, it could be demonstrated that the optimal dosage of NDZ-311w titanate coupling agent is inversely proportional to the grain size. TEM and XRD results showed that the grain size of ZnO nanoparticles were much smaller than that of ZnO nanorods, which can be the evidence for the equation. Otherwise, the surface modified ZnO nanoparticles displayed better dispersion than unmodified ones.

Abstract:

Abstract Durability, haptic, and optical appearance of wood are improved by coatings, which are nowadays prepared using environmentally compatible and less health-damaging materials. However, contemporary wood coatings have frequently a shortened service life compared to their traditional predecessors. New coating formulations would have a better performance if the adhesion to wood could be improved. In the present work, the chemical interaction between a titanium-based coupling agent, isopropyl triisostearoyl titanate (titanium agent, TA) and lignin has been studied by means of attenuated total reflectance-fourier transform infrared spectroscopy in combination with first principle predictions based on the density functional theory (DFT). In the infrared spectra, a new band at 1586 cm-1 was identified and the DFT predictions confirmed that the new band is because of the covalent bonds in the form of ether linkages between TA and lignin.

Abstract:

Chemical interactions between polyvinyl alcohol (PVA) and triethanol amine titanate chelate were studied using x-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The titanate chelate cross coupled the PVA solution and produced a viscous gel. The gel had a three-dimensional network structure containing -CPVA-O-Ti-O-CPVA- organic complexes. A new C(ls) signature at 285.7 eV and an O(ls) signature at 531.25 eV were associated with the formation of these complexes. The water of the PVA solution was physically retained in the gelled structure and was readily available for chemical reactions. The removal of this entrapped water was irreversible and led to a collapsed film of Ti-cross-linked PVA.

Abstract:

The effects of titanate as a coupling agent and some particulate nanoscale particles such as TiO2, CaCO3, and ZnO on thermal and mechanical properties of emulsion polyvinylchloride (E-PVC) were investigated by thermogravimetric analysis (TGA), and mechanical tests. In this research, it was found that, in the presence of nanoparticles of CaCO3, TiO2, and ZnO, the peak temperature of dehydrochlorination of E-PVC was shifted to higher temperatures, and the rate of mass loss was decreased. Also results of differential scanning calorimetry showed that the addition of nanoparticle of CaCO3, TiO2, and ZnO led to an increase in glass transition temperature. The impact strength, elastic modulus and toughness of the samples were enhanced after addition of 0–10 part of filer in hundred parts of resin (phr) nano-CaCO3, nano-TiO2, and nano-ZnO due to improvement of compatibility of the polymer and the nano-particles. Also UV and thermal stability of the samples were enhanced by means of the nanoparticles. It was found that, in the presence of titanate as coupling agent, content of additives that could be used in the composite of PVC shifts to higher amounts.

Abstract:

Functionalized layered double hydroxides (LDHs) based on a multi-modifier system composed of itaconic acid (ITA) and titanate coupling agent (NDZ-201) were designed and fabricated in this paper with the aim to develop high-performance fire retardant paper. The structure of LDHs were characterized using Fourier transform infrared spectroscopic analysis, X-ray diffraction analysis, thermogravimetric analysis (TGA), scanning electron microscopic analysis, cone calorimetry, and laser particle size analysis. The results showed that carbonate anions were partially replaced by ITA, whereas the titanate coupling agent was attached to the surfaces of the hydrotalcites. The limiting oxygen index (LOI), TGA curves, total heat release rate (THR), and heat release rate (HRR) indicated that as the addition of hydrotalcites increased, the modified LDHs’ LOI value and thermal stability noticeably increased compared to the unmodified hydrotalcites, and the HRR and THR of the material decreased. When the addition amount was 25%, the LOI of ITA-LDHs was 26.9%. However, the Mg-Al hydrotalcites adversely affected the strength index of flame-retardant paper; the modified hydrotalcites clearly reduced this effect, and the whiteness of paper increased and reached 83%.

Abstract:

Titanium dioxide (TiO2) is normally added into the rubber compounds as a white pigment and inorganic filler for an improvement of thermal property. TiO2 is also known to have an outstanding photocatalytic activity. This work investigates the properties of natural rubber (NR) compounds filled with 5 phr of nanoTiO2 (n-TiO2). Since the direct incorporation of n-TiO2 into NR encounters incompatibility problem, therefore two types of coupling agent (i.e. bis-(3-triethoxysilylpropyl) tetrasulfide (TESPT) and isopropyl trioleyl titanate (ITT)) are used. The coupling agent loading is varied in a range of 0-20 wt% relative to the n-TiO2. Mooney viscosities and minimum cure torque (ML) of the compounds increase with increasing coupling agent content and the ones with ITT show higher viscosity than the mixes with TESPT. The use of TESPT leads to shorter optimum cure time and higher torque difference compared to the use of ITT. The addition of n-TiO2 results in the improved modulus, reinforcing index and tensile strength compared to the unfilled vulcanizate. The presence of both TESPT and ITT significantly reduces a photodegradation efficiency. The difference in the properties and photocatalytic activity of n-TiO2 filled NR having TESPT and ITT as coupling agent indicates their possible different level of dispersion and interactions at the interphases.

Abstract:

The combination of nanoparticles with high relative permittivity and polymers with high dielectric strength offers a potential to obtain processable nanocomposites with high dielectric performance. In this work, polyvinylidene fluoride (PVDF)-barium titanate (BT) nanocomposites were prepared by spin-coating technique. The surface of BT nanoparticles was treated by titanate coupling agent NDZ101. The dielectric and energy storage properties of the system were studied as a function of BT content. The experimental results showed that the dielectric constant of the nanocomposites increased with the increase of BT content. Although pure PVDF material has the strongest dielectric breakdown strength, the discharged energy storage density Ue of the nanocomposites was greatly improved from 2.8 J/cm3 in pure PVDF film to 6.2 J/cm3 in PVDF/20 wt% BT film; due to larger polarization of the nanocomposite.

Abstract:

Waterborne acrylic resin is widely used as a binder of waterborne printing ink because of its excellent comprehensive properties. However, its further developments and applications are hindered by its poor UV resistance and water resistance. Therefore, an approach to prepare acrylic resin with excellent UV resistance and water resistance is described in this present study. The nano-TiO2/SiO2 composite particles were first modified with a silane coupling agent (KH-570) and a titanate coupling agent (NDZ-101) and then embedded into acrylic resin via a blending method. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermogravimetry analysis (TGA) were applied to investigate the structure and morphology of the modified nano-TiO2/SiO2 composite particles. The effects of the modified nano-TiO2/SiO2 composite particles on the UV and water resistance of the acrylic resin were investigated by UV spectroscopy and water resistance analysis. The weight loss of modified nano-TiO2/SiO2 was about 20% when heated to 600°C, which indicated that the nano-TiO2/SiO2 composite particles were modified by the coupling agents successfully. The UV-Vis spectra of acrylic resin showed that the UV resistance was improved upon the addition of nano-TiO2/SiO2. The water absorption of the nano-TiO2/SiO2-acrylic resin was less than 5%, indicating that the water resistance of the material was improved.

Abstract:

The surface of potassium titanate whisker (PTW) was coated with Al2O3 derived from NaAlO2 solution via a liquid deposition method, and coupling agent KH570 was used to treat the surface of Al2O3 coated PTW. Scanning electron microscope (SEM), X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and surface contact angle measurement were used to characterize the effect of surface modification. The results showed that the surface of PTW was uniformly coated by Al2O3 nanoparticles. After modified by KH570, the modified Al2O3/PTW showed better dispersion in ethanol solvent and the surface of modified Al2O3/PTW became more hydrophobic-lipophilic than that of modified uncoated PTW. It is indicated that the modified Al2O3/PTW could be dispersed much better than the modified uncoated PTW in organic phase.
