This project will bring economic, medical and environmental benefits, with improved product performance and manufacturing processes for everyday industrial items relevant to a large industrial sector with significant employment in Australia: inks and paints (for example, surface coatings that can be applied more rapidly without clogging the jets); better means of preventing the fouling of industrial membranes; and improved materials for biomedical applications, with more desirable interactions between living cells and body fluids. These advances will also speed the replacement of solvent-based lacquer paints - detrimental to both environment and user - with water-based products of high quality.Read moreRead less
Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is a ....Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is applicable to polymerization kinetics studies, as well as providing new means for the determination of materials lifetimes. The development of pro-fluorescent markers as indicators for polymer degradation would be a significant outcome for materials where component failure has a major negative impact.Read moreRead less

Summary
Multi-dimensional polymer characterization facility. The microstructure of polymers dominates their physical properties. This integrated facility will create a world-leading means of characterizing in multiple dimensions the microstructure of complex polymers, eg copolymers and branched polymers. The facility will yield information on the distributions of chain end-groups, monomer microstructure, and branches, as functions of molecular weight. The facility will provide otherwise unobtainable dat ....Multi-dimensional polymer characterization facility. The microstructure of polymers dominates their physical properties. This integrated facility will create a world-leading means of characterizing in multiple dimensions the microstructure of complex polymers, eg copolymers and branched polymers. The facility will yield information on the distributions of chain end-groups, monomer microstructure, and branches, as functions of molecular weight. The facility will provide otherwise unobtainable data for a set of projects exploring questions ranging from how new synthetic materials with tailor-made properties can be created, through to how our understanding of natural polymers can be advanced to improve crop utilization.Read moreRead less
