摘要：

A stable superhydrophobic surface was fabricated by solidifying poly(epoxy-terminated polydimethylsiloxane-co-bisphenol A) [P(ETPDMS-co-BPA)] copolymer on a rough substrate. The low surface energy of the copolymer and the geometric structure at micrometer scale of the surface contribute to the superhydrophobic property. The as-prepared surface shows stable superhydrophobicity over a wide pH range (1-14) and the wettability is excellent stable to heating, water, corrosive solution and organic solvent treatments. The procedure is simple and time-saving as well as utilizing non-fluorine-containing compounds. (C) 2007 Elsevier B.V. All rights reserved.
