摘要：

We have performed extensive studies on the long term chemical stability of a superhydrophobic coating comprised of silicone nanofilaments. Durability was tested by immersion in various liquid media over a period of 6 months. The coating properties were monitored by static contact angle and sliding angle measurements. Changes in surface topography were examined by scanning electron microscopy. The coatings show an exceptional stability in organic solvents, neutral and mildly acidic aqueous solutions and mildly acidic detergent solutions. The superhydrophobic coating properties are stable for several days in mildly basic and strong acidic solutions but deteriorate fast under strong basic conditions. (c) 2007 Elsevier B.V.
