Silicon-Containing Polymers and Composites.

摘要

Many hydrophobic surfaces exist in nature, but there is no naturally occurring oleophobic surface. There is plenty of academic and commercial interest in the development of oleophobic surfaces. The focus is on commercially available textiles. This presentation shows that fluoroPOSS are superhydrophobic. FluoroPOSS polymer composite surfaces can be superhydrophobic and superoleophobic. Superhydrophilic and superoleophobic surfaces have been developed. Such sufaces are ideal for the separation of both free-oil and oil- water emulsions. These membranes, for the first time, allow continuous-flow oil- water emulsion separation. Functionality will allow the covalent attachment of these low energy materials to substrates of choice.
