Summary on Grant Application Form
Low surface energy materials (LSEMs) are obtained by attachment of surface layers to substrates. The cause of low surface energy is the underlying chemical structure of the interfacial layers: the ability to control surface properties being the direct consequence of chemical structure. Since the first development of anti-wetting surfaces, it has always been necessary to employ long Fluorinated tails (>7 x CF2/CF3 groups) in the surfactant additives. There are numerous applications of LSEMs today, such as printing, painting, adhesion, metal-plating, emulsification/suspension (medical, cosmetic, food packaging, etc.), washing (electronics, clothes, etc), antifogging and repellent surfaces (self-cleaning windows, water-proof textiles, anti-snow, anti-fog surfaces, papers, fibers, etc.). Therefore, development and optimization of LSEMs has attracted much attention, and a wide variety of useful LSEMs can be obtained by Fluorinating surfaces. Unfortunately, this has dramatic environmental consequences because of the persistence and bioaccumulation of Fluorocarbons (FCs). [Food Addit Contam. 2005, 10, 1023-31, Environ. Sci. Technol. 2006, 40, 32-44]. As outlined below, this project is centred on intelligent programmed molecular design of hydrocarbon (HC) surfactants, which will generate similar surface properties to the undesirable FCs.
