Polymers are being used for non-stick coatings, anti-fouling technology, precision drug delivery, medical diagnosis, imaging, and many other applications.
Associate Professor Cyrille Boyer’s ideas are built on the revolutionary RAFT techniques (a technique to precisely control how small molecules are linked together to form large polymer chains) for which Professor David Solomon and Dr Ezio Rizzardo received the 2011 Prime Minister’s Prize for Science. His latest technology uses light and chlorophyll to catalyse the production of polymers.
New lubricants containing star-shaped polymers have hit the market, thanks to Australian polymer technology. Lubrizol Corporation has launched the first commercial products developed using CSIRO’s Reversible Addition Fragmentation chain Transfer (RAFT) polymer synthesis process.
CSIRO chemist Dr Ezio Rizzardo says the RAFT process allows much greater flexibility and potential for polymer synthesis, compared with conventional methods. “Conventional polymerisation is a relatively simple process with two ingredients: large amounts of monomer and a small amount of an initiating agent. You apply heat; a chain reaction starts and runs to completion, making polymer chains that can have widely varying lengths.” Continue reading Star-shaped polymers boost engine performance→
Sugarcane is one of nature’s most efficient natural converters of sunlight, carbon dioxide and water into fuel or biomass – and as such, it is perhaps the world’s fastest growing and largest biomass agricultural crop.
