Studies on wettability of polypropylene/methyl-silicone composite film and polypropylene monolithic material

A polypropylene/methyl-silicone superhydrophobic surface was prepared using a simple casting method. Varying the ratio of polypropylene and methyl-silicone results in different surface microstructure. The wetting behavior of the as-prepared Surface was investigated. A polypropylene monolithic material Was also prepared. Its superhydrophobicity still retains when the material was cut or abraded. The as-prepared material can also be used to separate some organic solvents from water. (C) 2008 Elsevier Inc. All rights reserved.
