The Australian automotive export market (vehicles, parts, engines) is worth approximately $4,500 million p.a. and is a major employer in many areas. A reliable, cheap and efficient method for preparing polymer surfaces for painting will significantly benefit that market. The ability to manufacture quality, cheaper, lightweight parts improves the competitiveness of the local automotive industry. More importantly, a technology for production of cheap, high quality painted polymer surfaces vastly improves the competitiveness of local component manufacturers who supply to international vehicle manufacturers. This project falls under the National Research Priority Area 'Frontier Technologies for Building and Transforming Australian Industries'.Read moreRead less
Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettab ....Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettable to non-wettable with changing temperature and humidity. These self-cleaning polymer surfaces with environmentally responsive properties will add value to pre-painted steel products and other coatings.Read moreRead less
Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pi ....Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pigment regrind stage. The research will investigate the development of a highly durable dry-coated pigment utilising a novel high dielectric coating. This development has the potential to ensure the partner company's future competitiveness through reduced processing costs and improved product performance.Read moreRead less
An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms ....An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms of adhesion failure and improve our fundamental understanding of the problem. The results will be used to enable the selection of process conditions and lacquers that are more robust and reduce the incidence of adhesion failure.Read moreRead less
Mechanisms and modelling of gels for protein separation. Gradipore approached Sydney University to collaborate on fundamental science needed to improve polymer gels for separation and characterization of proteins. These gels have many applications: e.g. proteomics and diagnostics. Presently, control of polymer microstructure in the synthesis of these gels is by trial and error.

Gradipore approached Sydney University to collaborate on fundamental science needed to improve polymer gels for separation and characterization of proteins. These gels have many applications: e.g. proteomics and diagnostics. Presently, control of polymer microstructure in the synthesis of these gels is by trial and error. This project will create an accurate model of the process so pore size can be predicted. This involves novel work in experimental and theoretical methods developed by the Sydney University group. The result will be qualitative and quantitative understanding which can be subsequently used to tailor-make gels for new applications.Read moreRead less

Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if ef ....Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if effective methods can be found to minimise such damage. This project proposes to study a novel technique, in which blends of hydrophobic polymer additives are used to increase the stability of geomaterials subjected to varying moisture levels and traffic loading.Read moreRead less
Electronic and Optical Properties of Doped Titanium Dioxide. Titanium dioxide, is widely used as a white pigment, owing to its high refractive index, second, only after diamond. Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles.

Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify the specific electronic cause of the yellowing process, the nature of the Al defect,it's effect on the electronic structure of rutile, and the electronic perturbations that may occur when other dopants are used.Read moreRead less

The aim of the proposed research is to develop novel surface-active polymers with complex architectures and more efficient strategies for the synthesis of surface-active polymers in general. We will exploit the polymerization characteristics of the novel catalytic chain transfer and radical addition-fragmentation transfer polymerization techniques to achieve polymerization control that has been virtually impossible hitherto. The proposed research will thus make accessible a wide range of novel surface-active polymers that have been impossible to synthesise to date, and which we expect to be more efficient and hence leads to greener technologies.
