Biomimetic templating radical polymerisation in nanoreactors. The aim is to develop methodology for synthesis of polymer with hitherto inaccessible control of the microstructure by free radical means, that is the molecular weight distribution and monomer sequences. This will be achieved by combining the two concepts of biomimetic templated radical polymerisation and polymerisation in nanoreactors in the form of submicron-sized micelles or droplets. Scale-up of the methodology will be developed b ....Biomimetic templating radical polymerisation in nanoreactors. The aim is to develop methodology for synthesis of polymer with hitherto inaccessible control of the microstructure by free radical means, that is the molecular weight distribution and monomer sequences. This will be achieved by combining the two concepts of biomimetic templated radical polymerisation and polymerisation in nanoreactors in the form of submicron-sized micelles or droplets. Scale-up of the methodology will be developed based on an environmentally friendly approach whereby miniemulsions are generated using carbon dioxide. Increased ability to control the polymer microstructure will enable advanced design of functional polymers with far-reaching applications in materials science, nanotechnology and nanomedicine.

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

By fully taking advantage of excellent affinity of water with polar layered silicate and polar polymer, an innovative approach to fabricate thermally stable polymer/layered silicate nanocomposites via melt extrusion with the aid of water/water vapour will be developed. In this process, the pristine layered silicate will be directly exfoliated into individual layers with nanometer thickness and high aspect ratio, and uniformly dispersed in a polymer matrix. This novel approach is environmentally benign and cost-effective since no alkyl ammonium surfactants are required. The resultant nanocomposites will exhibit excellent barrier properties, high thermal stability, environmental durability and superior mechanical properties. These qualities make them very attractive for many applications in the automotive and packaging industries.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

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.
