Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it r ....Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it represents the stress amplitude below which fatigue failures should not occur. Its existence in unnotched pipes and in the newer PVC materials is uncertain. This project will quantify fatigue thresholds and the mechanisms involved in crack initiation in uPVC , mPVC and oPVC.Read moreRead less

High performance thermoplastic starch polymer films for controlled barrier and delivery. This project will deliver state of the art developments in high performance sustainable plastics. Specifically the project will develop new biopolymers for high-performance applications, such as smart packaging, biomedical materials and drug delivery systems.
Development of PVC-Based Polymer Nanocomposites. The aim of the project is to develop a PVC polymer nanocomposite material to be used in water pipelines. It has been found that the inclusion of a nanoparticle phase, in this case calcium carbonate, leads to increases in strength, stiffness, toughness and abrasion resistance. This proposed project will develop and assess an optimum material in addition to investigating the mechanisms of deformation.
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
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.

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.

Nanotechnology is one of the most rapidly growing areas in the 21st century. Its world market is expected to reach US$2.6 trillions in 2014, valued at 15% of global manufacturing output. The use of clay nanofillers as polymer reinforcement is an emerging cutting-edge research and of paramount importance in Australia in view of its heavy dependence on mineral industries. The project will tackle the core problems in this field. The research outcomes will lead to highly value-added mineral products and better process control. Furthermore, the application of polymer nanocomposites in automotive and packaging industries will significantly decrease energy consumption and CO2 emission, and increase the shelf-life for food and beverage.

Polymers and nanocomposites are increasingly being used in new, high value applications as diverse as medicine, structural engineering, optics and electronics. In order to control and understand polymer performance, a detailed knowledge of the chemical structure at all stages in their lifecycle is required - in the liquid, rubber and solid states and during degradation. This application seeks to establish a coordinated Polymer Spectroscopy Network using new forms of infrared and NMR spectroscopy to probe samples (usually of an non-planar geometry) in a range of configurations. These will be used simultaneously with other techniques such as rheology or thermogravimetry, and will produce capabilities unique in Australia.Read moreRead less
