Abstract
|
Aluminum sheets were furnished with a water-repellent composite layer consisting of microroughened alumina, chitosan (CHS), and poly[octadecene-alt-(maleic anhydride)] (POMA). CHS was electrochemically deposited or spin-coated. In a subsequent reaction step, POMA was covalently bonded onto the immobilized CHS layer. The produced composite layers showed superhydrophobic properties, which are indicated by the water contact angles >150° and negligible hysteresis. Cross-linking reactions of the CHS layer were able to enhance the layer stability. The superhydrophobic surface properties were also maintained after abrasion of the protruding polymer-coated alumina peaks. This is due to a CHS/POMA reservoir incorporated in the microroughened alumina surface region.
