Abstract:
Characterization of chitosan / layered silicate nanocomposites obtained by solution-mixing technique, having different compositions including treated and untreated montmorilonite (MMT) has been performed. The optimum amount of MMT and also the effect of nanoparticles type on nanocomposite properties by DSC, X-ray diffraction and TG measurements have been established. The chitosan chains were inserted into silicate layers to form the intercalated nanocomposites. The interlayer distance of the silicates in the nanocomposites enlarged as their amount increased. The stiffness and thermal stability enhanced.

Abstract:
Layered silicates, as bitumen modifiers, have received increasing attention. The main objective of this study was to evaluate the influence of layered silicates on bitumen properties. For this study, montmorillonite (MMT), rectorite (REC), organic montmorillonite (OMMT), and organic rectorite (OREC) were selected. The layered structure type of layered silicates was characterized by SEM (scanning electron microscope) and XRD (X-ray diffraction diffractometer). Tests for determining high-temperature properties included viscosity, DSR (dynamic shear rheometer), and TG (thermogravimetry) tests, and studies for determining the low-temperature properties were conducted by BBR (bending beam rheometer) and DSC (differential scanning calorimetry) tests. Our results show that MMT, REC, OMMT, and OREC were all intercalated structures. OREC had the largest d001 interlayer space, followed by REC, OMMT, and MMT. OREC improved the high-temperature property of virgin bitumen more effectively than OMMT. Meanwhile, REC-modified bitumen exhibited a high-temperature property similar to OMMT-modified bitumen. When compared with REC and OREC, MMT and OMMT were less efficient in reducing the low-temperature properties of virgin bitumen, and OMMT was the least efficient. Therefore, it can be concluded that the nature of pristine layered silicates has a great impact on the high- and low-temperature properties of bitumen. Moreover, organic treatment can simultaneously improve the high- and low-temperature properties of layered silicate-modified bitumens.

Abstract:
The objective of this study was to prepare and characterize hybrid films based on layered silicates with a tetracationic porphyrin dye 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)porphyrin (TMPyP) intercalated in the inorganic matrix. The properties of the TMPyP cations in the materials were compared with those of other systems (solutions, colloids) characterized mainly by absorption and fluorescence spectroscopies. Linearly polarized absorption spectroscopy, X-ray diffraction (XRD), and fluorescence microscopy were used as well. Using appropriate layered silicate templates, applying the premodification of the inorganic component with hydrophobic alkylammonium surfactants and selecting an appropriate method, one can prepare the materials of broadly variable spectral properties of the dye. The spectral variation takes place while preserving the photochemical activity of TMPyP. The interpretations of spectral changes are based on the structural changes of the TMPyP molecules adsorbed on layered silicate surface related to the flattening of cationic pyridinium substituents.

Abstract:
Large icy Kuiper Belt Objects (KBOs) such as Pluto have observed densities on the order of 1.8 - 2.0 g cm-3. This indicates that they are made up of some combination of ice and silicate material; their size further implies that they will possess a differentiated structure with ice dominating towards the surface and silicate material dominating towards the core. A series of impact experiments using the University of Kent's light gas gun have been carried out in order to determine the impact strength of spherical layered ice-silicate targets that reflect the suspected structure of these bodies. Impacts are also carried out on unlayered ice-silicate targets and pure ice targets for the purposes of comparison. Impact velocities ranged from 1 to 7 km S-1 using a range of projectile sizes and materials including stainless steel, titanium, aluminium and copper. Data from previous work undertaken at the University of Kent is incorporated in order to provide a more complete picture of target behaviour.

Abstract:
Polymer layered silicate nanocomposites (PLSN) have attracted great interest because they exhibit remarkable improvements in materials properties relative to pristine polymers. Successful formation of a PLSN is critically dependent on generation of very high interfacial area in the composite. This is accomplished when the stacks of silicate platelets (tactoids) split into discrete platelets. The latter phenomenon is known as exfoliation and is strongly influenced by interfacial chemistry (i.e. structure and properties of the interface or interphase) associated with the edge and basal surfaces of the silicate platelets, chemical modification (usually with quaternary alkyl ammonium halides) of the latter and the resulting effect on interactions between the platelets themselves and polymer chains. Interactions between sodium montmorillonite (Na-MMT)/organically modified montmorillonite (o-MMT) and a variety of probes, some of which are intended to model the structures present in the components of a polyurethane (PU), epoxy resin and polystyrene system (PS), have been studied. The adsorption process was characterised using flow microcalorimetry (FMC) in conjuncqon with diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS), and wide angle x-ray scattering (\VAXS). Adsorption of hydrogen bondable groups, such as alcohol, ether, amine probes, onto Na-MMT was dominated by the hydrogen bonding interactions with hydrated Na+ ions and with the hydroxyl groups present at the platelet edges. Moreover, stronger interactions with hydrated Na+ ions led to greater retention of the probes after the desorption process. When the Na-MMT was moisturized at ambient atmosphere, hydrogen bondable probes showed a reversible adsorption. In contrast, chemical adsorption (reaction) dominated the adsorption of the isocyanate probe onto Na-MMT; the latter reacted either with the platelet edge hydroxyl groups forming a urethane linkage or with pre-adsorbed ambient water molecules adsorbed onto Na-MMT ultimately forming a physically adsorbed urea. In the case of o-MMTs, when only the platelet edge hydroxyl groups were available, hydrogen bondable probes showed a reversible adsorption. Reactions between reactive probes, including isocyanate and epoxide probes, and surfactant functional groups (OH and COOH groups) are affected by the gallery structures, such as the arrangement of surfactant within the galleries and level of surfactant intercalated. Adsorption of aromatic probes, including styrene, ethylbenzene and polystyrene, was dominated by the relatively weak dispersive interactions with the basal surfaces of o-MMT, and was significantly affected by the gallery structures ofo-MMT (surfactant level and surfactant structure). This study has provided valuable new insight into interactions in nanocomposite materials.

Abstract:
The demands made of materials have resulted in the formation of complex composite structures; one such example of these is nanocomposites. This study is primarily devoted to the preparation and characterisation of nanocomposites. Reactively cast and reactively extruded nanocomposite strategies for the preparation of polyamide-6 composites were compared. The catalyst and activator system selected was based on an industrially successful combination. The extruder screw and barrel configuration used had previously been proven effective for the reactive polymerisation of polyamide-6. The principal objectives were the investigation of the influence of layered-silicates on both the microstructure and the physical properties of the composites. As well as the analysis of the mechanisms that influence the physical performance of the materials produced. The characterisation of the filler-matrix microstructure and its effect on physical properties of the composites were investigated using a range of chromatographic, microscopic, thermal and X-ray analytical techniques. Selected mechanical properties were measured using standard test procedures. Therefore results obtained and subsequent trends observed in reaction cast and reaction extruded nanocomposites could be compared and contrasted. The influence of the polymerisation conditions, residual monomer content and the nature of the composite structure produced were considered. It was observed that the nature of the matrix crystalline structure could be greatly influenced by the material composition, method of preparation and processing technique. The crystal form of the spherulites present appeared to be the key factor in influencing mechanical strength. The treatment of the silicate-layered clay successfully increased the inter-layer spacings, which was further increased by the presence of high shear forces.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, February 2003.
Includes bibliographical references.
The fundamental role of the layered-silicates in a styrene-butadiene-styrene triblock copolymer (SBS) as a function of layered-silicate dispersion during deformation was investigated. Predominantly immiscible composites of mixed morphology provided the initial proof that dramatic alteration of the SBS deformation behavior exists, but a clear understanding of the nature of reinforcement was precluded due to the fiber symmetric orientation of the SBS and the mixed clay morphologies. Following the theory of Vaia and Giannelis, use of a more hydrophobic organically modified clay resulted in an intercalated morphology with a near single crystalline texture of the SBS due to roll-casting. Significant heterogeneous deformation was observed at ambient conditions as well as at elevated temperature as verified through Cohen's affine deformation model in combination with Kratky's scattering pattern model. The intercalated morphology shows little or modest mechanical property enhancements at all temperatures studied. Exfoliated nanocomposite was produced by functionalization of the clay surfaces with polystyrene, altering the enthalpic interactions. Entropic interactions were also controlled by varying the molecular weight of the surfactant and the grafting density and shows remarkable agreement with the theory proposed by Balazs et al. Due to the increase surface volume ratio of the clay, a flipping transition of the block copolymer morphology was observed during roll-casting producing a near single crystalline parallel/parallel clay/BCP orientation. The modulus was relatively unaffected whereas the toughness increased significantly due to an earlier onset of strain hardening.

Abstract:
The aim of this study is to investigate the film blowing processing of various polyamide 6-based layered silicate nanocomposites (LSN’s) and to correlate their processing behaviors to the underlying rheology and structure. In-situ polymerized nanocomposites were found to possess a wider processing window compared to the base PA6. Shear and dynamic rheological measurements were employed to correlate the rheological behavior of the nanocomposites to the bubble formation and stability in the film blowing process. The in-situ plymerized LSN melts having higher elastic modulus (G′) were found to perform better in the film blowing process. DSC measurements indicated that nanoclays induce the γ type of crystallinity, which may also play a role in film blowing behavior.

Abstract:
Polymer/clay nanocomposites currently attract immense interest from both research and industrial communities. By dispersing at the molecular level a tiny amount of clay within a polymeric matrix, a wide range of properties can be significantly improved. The efficiency of the clay (layered silicate) in improving the properties of the polymer materials is primarily determined by the degree of its dispersion in the polymer matrix. To promote the molecular and stable dispersion of the clay layers, the clays should be organically-modified with onium salts. In this work, nylon-6 nanocomposites based on two types of commercial organoclays were prepared by melt blending via single-screw extrusion. The good dispersion of clay in the nylon-6 nanocomposites was confirmed by X-ray diffraction and transmission electron microscopy. The influence of the dispersed nano-clay fillers on the thermal and mechanical properties of the resulting nanocomposites was characterized using thermogravimetric analysis and nanoindentation.

Abstract:
The field of polymer-clay nanocomposites has attracted considerable attention as a method of enhancing polymer properties and extending their utility. Layered silicates dispersed as a reinforcing phase in a polymer matrix are one of the most important forms of such inorganic-organic nanocomposites, making them the subject of intense research. We have recently prepared several thermoset-based nanocomposites with improved thermal and mechanical properties. This paper is primarily focused in studying the effects of nano clay particles such as montmorillonite on improving mechanical and thermal properties of the polymer matrix composite. Epoxy and vinyl ester nanocomposites were prepared by adding different weight percentages (0.5%, 1%, 2%, 5% and 10%) of montmorillonite nano clay particles to epoxy and vinyl ester matrices. The results show significant improvements in mechanical and thermal properties of the nanostructured materials with low loading of organo silicates. Thermal property measurement includes dynamic mechanical analysis (DMA). Mechanical properties such as flexural strength and flexural modulus of polymer matrix were improved in nano structured materials owing to their unique phase morphology and improved interfacial interactions. Molecular dispersion of the layered silicate within the cross-linked matrix was verified using Wide Angle X-Ray Diffraction (WAXD) and Transmission Electron Microscopy (TEM) revealing the intercalated nanocomposites were formed.
