Artificial Proteins for the Control of Colloid and Surface Properties

Grant number: DP0664051

Abstract

A large amount of Australia's wealth arises from mining and the processing of small (colloidal) particles. This project will develop new coatings for particles, which will allow better control of the properties of particle suspensions. Control of surface properties is also important in the preparation of ceramics and in the preparation of implants and biosensors. The development of new coatings will also offer opportunities for improved performance in these areas. Many existing coating technologies rely on procedures using organic solvents, which are hazardous to human health and the environment. The proposed research will develop coatings that are made and used in solutions of water only, t..
