Novel Tough Polymer Composites. Advanced composites are used in high value-added applications such as computer chip packaging and aerospace applications. In these applications epoxy systems are used despite their inherent brittleness. Much research has focused on toughening epoxy systems, but most tougheners cause a reduction in processing or material properties. This project focuses on developing novel epoxy tougheners during the polymerisation of the epoxy-based composite. Specifically we will ....Novel Tough Polymer Composites. Advanced composites are used in high value-added applications such as computer chip packaging and aerospace applications. In these applications epoxy systems are used despite their inherent brittleness. Much research has focused on toughening epoxy systems, but most tougheners cause a reduction in processing or material properties. This project focuses on developing novel epoxy tougheners during the polymerisation of the epoxy-based composite. Specifically we will use novel hyperbranched [star-like] polymers that have excellent processing properties, high reactivity for structure control and the ability to control toughening at the molecular and macroscopic level to produce novel technology for advanced composites.

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
Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less
Polymerization Mechanism and Kinetics of 1,1-Disubstituted Monomers. This project focuses on two exciting research areas: (I) we have found that an oxygen atom b to the double bond activates radical polymerization, making a whole new family of polymeric structures accessible, and (II) we have strong preliminary data that demonstrates a very large solvent effect on propagation and termination reactions for acrylic monomers with an a-CH2OH functionality, suggesting that significant control can be ....Polymerization Mechanism and Kinetics of 1,1-Disubstituted Monomers. This project focuses on two exciting research areas: (I) we have found that an oxygen atom b to the double bond activates radical polymerization, making a whole new family of polymeric structures accessible, and (II) we have strong preliminary data that demonstrates a very large solvent effect on propagation and termination reactions for acrylic monomers with an a-CH2OH functionality, suggesting that significant control can be exerted over the polymerization process using additives. Additionally, we demonstrate that polymers containing repeat units with an a-CH2OH functionality can undergo reversible cyclization, enabling a whole range of novel functional materials.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
