Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks.

Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description of filled soft viscoelastic solids, which include compressibility and yielding - two important new features.Read moreRead less

New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high tec ....New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high technology industries, as well as in harsh environments. Because we will be able to manipulate the structure and observe property changes, it should also give us a greater insight into the adhesion mechanisms used by many small animals and bugs.Read moreRead less

Single molecule actuators. The study of actuation processes in single molecules will lead to the development of improved advanced materials for Australian industry and, ultimately, to the more futuristic and exciting nanotechnologies. The research will improve our understanding of how polymer artificial muscles function, so that these materials can be further developed to meet the demand from industry. Applications include biomedical devices, robotic applicators and various machine parts. In ....Single molecule actuators.

The research will improve our understanding of how polymer artificial muscles function, so that these materials can be further developed to meet the demand from industry. Applications include biomedical devices, robotic applicators and various machine parts. In addition, the research will also contribute to one of the greatest promises of nanotechnology: the development of molecular machines. We will demonstrate the mechanical forces and movements possible from single molecules so that the design of useful nano-machines can begin.Read moreRead less
Nanostructured materials by controlled photopolymerization. Photo-polymerization is an important and flexible means of converting a crosslinkable monomer into a solid and has application ranging from lens production to photo-lithography. This project aims at developing the technology of producing multi-phase structures of controllable morphology by selective and independent dual photo-polymerization of blends of crosslinkable monomers at controlled rates. These morphologies may have applicatio ....Nanostructured materials by controlled photopolymerization. Photo-polymerization is an important and flexible means of converting a crosslinkable monomer into a solid and has application ranging from lens production to photo-lithography. This project aims at developing the technology of producing multi-phase structures of controllable morphology by selective and independent dual photo-polymerization of blends of crosslinkable monomers at controlled rates. These morphologies may have applications in toughening polymers with minimum loss in strength and optical transparency, abrasion resistant coatings, tissue engineering (where the phases have differing biodegradability), in microfluidics, and microelectro-mechanical systems (where sub-micron channels/domains are required) or in membrane separation.Read moreRead less
