The project aims at advancing the synthetic limits and broadening the synthetic scope of living free radical polymerization and thus enhancing the library of polymer structures available for applications ranging from drug delivery to opto-electronics. Current material design for these applications is yet to reach its full potential through innovative synthetic approaches. The proposal critically underpins and further advances Australia's leading position in both breakthrough science as well as advanced materials. Due to its significant scientific breadth and large coverage of both synthetic and physical aspects of polymer science, the project also provides a significant platform for research training at both honours and PhD level.Read moreRead less
Nanogels: Next Generation Polymeric Particles. The existing knowledge in the formation of polymeric networks limits the technological development of polymer materials. This project will introduce new polymeric particles, called nanogels to open a new area in new polymeric architecture research. A number of new structures based on the nanogels will be developed.

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
Mechanisms in Catalytic Chain Transfer Polymerization. The aim of the proposed research is to gain more insight into the mechanisms underlying catalytic chain transfer polymerization, a relatively recent controlled radical polymerization technique which is finding an increasing number of industrial applications, especially in the paint and coatings industry.

The aim of the proposed research is to gain more insight into the mechanisms underlying catalytic chain transfer polymerization, a relatively recent controlled radical polymerization technique which is finding an increasing number of industrial applications, especially in the paint and coatings industry. An improved understanding of the catalytic chain transfer process, of which some very important features are still poorly understood, will ultimately lead to better catalyst design and improved process and product control. This in turn will lead to novel polymeric materials.Read moreRead less
Synthesis of oligomers in dense carbon dioxide. The aim of the project is to develop a novel technique for the synthesis of low molecular weight polymers (oligomers) using dense carbon dioxide as a polymerisation solvent. The use of elevated pressure is the major impediment to the commercialisation of such technology. The technique proposed in this project will enable oligomers to be produced at greatly reduced operating pressures and may lead to a more general procedure for conducting other t ....Synthesis of oligomers in dense carbon dioxide.

Controlled/living radical polymerization is a technique for precise synthesis of polymer by radical polymerization, which has revolutionized polymer synthesis in terms of accessible polymer structures. However, controlled/living radical polymerization has yet to gain a strong foothold in industry mainly due to problems associated with its implementation in (aqueous) dispersed systems. The present Proposal addresses this key challenge by a novel environmentally friendly and versatile method for aqueous miniemulsion preparation by use of compressed carbon dioxide. Controlled/living radical polymerization in dispersed systems generates polymeric nanoparticles, which are of importance in many advanced and emerging technologies.Read moreRead less
