Abstract (sommario):

Layer thickness measurements are used to investigate polymer adsorption and possible conformations of adsorbed polymer.<br>In a first step, photon correlation spectroscopy (PCS) is used to monitor the layer thickness at different ratios of polyethylene oxide (PEO) per polystyrene (PS) latex spheres. Comparison of the polymer concentration at which the equilibrium layer thickness was attained with the concentration where the adsorption isotherm reached its plateau leads to a proposed three step adsorption process. Kinetic studies of the layer thickness build-up also support this mechanism. Poly

Abstract (sommario):

In recent years there has been increasing interest in novel forms of surfactants. Of particular interest are gemini surfactants, which consist of two conventional surfactants joined by a spacer at the head groups, as they exhibit lower critical micelle concentrations than can be achieved by conventional surfactants. In this work, the self-assembly behaviour of several nonionic gemini surfactants with polyethylene oxide head groups (GemnEm, where n (= 20) is the number of carbons per tail and m (= 10, 15, 20 and 30) is the number of ethylene oxides per head group) were investigated.

Abstract (sommario):

On a papermaking machine, fines and colloids are retained in a paper sheet. The most important particle interactions are among particles having a high weight fraction and a short characteristic interaction time. Most of these interactions follow Langmuir kinetics, in which the flocculation efficiency is one of the important parameters. To enhance retention, many retention aids are available, one of which is neutral polyethylene oxide (PEO) used in combination of a phenolic cofactor (CF).<br>In this work, a new model was derived in which all possible interactions were considered and assumed to

In this thesis the protein resistive nature of polyethylene oxide brushes shall be investigated.

This procedure will allow the accurate control of the grafting density of PEO brushes. The crystallisation and oxidation of PEO brushes is also briefly investigated. Ex situ ellipsometry experiments will show that the adsorbed amount of protein is related to the surface coverage of polymer. supporting the random sequential adsorption theory (RSA-model) of Kati

A novel approach was used to synthesize bioactive polyurethanes by applying polypropylenimine octaamine dendrimers as the chain extenders, while another approach trying to incorporate star PEO (polyethylene oxide) directly into polyurethane failed to attain appropriate polymers. A protection/deprotection strategy was used to incorporate the dendrimers into the polyurethane chains, then PEO was chemically attached after deprotection to increase the biocompatibility of the material. A generation 2.0 polypropylenimine octaamine dendrimer which has eight arms ending with amine groups, was used for

Abstract (sommario):

Adding polyethylene oxide (PEO) at the wet end of a paper machine, can result in an increase in retention of the fine particles. The results obtained with PEO and the cofactors (SNS, MPR, and CAR), are discussed in terms of the association-induced polymer bridging mechanism.<br>Dynamic Light Scattering (DLS) of polymer solutions revealed that each of the three cofactors are forming complexes with PEO. CAR radically increased the apparent diameter of the PEO chains, and MPR seems to decrease it. In latex suspensions, the SNS was found very efficient in the sequence latex-polymer-cofactor (LPC),

Abstract (sommario):

Membrane structure modification is a common approach to enhance membrane properties and performance. For example, the addition of dopants to the membrane casting solution has been observed to increase hydrophilicity, alter surface and internal pore structure, increase thermal and mechanical resistance, and impart anti-fouling properties. In this study, it was evaluated how the addition of individual and simultaneous nanoclay and polyethylene oxide (PEO) dopants affected the structure and performance of polysulfone (PSU) ultrafiltration membranes.

Abstract (sommario):

Polymer nanocomposites have attracted great interest over many years, because of the enhanced properties exhibited by such systems. However, it is only recently that the electrical characteristics of this class of material have begun to be studied in detail. Whenever fillers are added to a host polymer matrix, dispersion is of critical importance since, while a well dispersed nanophase may be beneficial, poor dispersion can have negative consequences. Hence, for the nanocomposites to be used appropriately and provide the best properties, a method for observing the dispersion within the matrix

Abstract (sommario):

A combination of surface analytical techniques, colloid probe Atomic Force Microscopy (AFM) and X-ray Photoelectron Spectroscopy (XPS) was used to optimise the grafting density of covalently attached 5, 20 and 40 kDa methoxy-terminated PEO layers (under marginal solvation (cloud point) conditions for the PEO molecules). The combination of these techniques allowed us to relate the PEO layer density and molecular conformations to the range, magnitude and types of forces generated by coatings of various grafting densities. The key optimisation parameter was the grafting time with the concentratio

In the pursuit of lower cost intumescent flame retardant (IFR) systems, the compound expandable graphite (EG) was identified.

It was theorised that this may be remedied either through ion exchange of the interstratified ions with low glass transition ions or through use in binary systems with other compounds. Two classes of commercial EG were identified, namely a low and a high expansion onset temperature EG compound. Ex
