Wetting behavior of a SiO2-polystyrene nanocomposite surface
A SiO2-polystyrene (PS) nanocomposite surface was prepared with a simple method. The wetting behavior of the as-prepared surface was investigated. It was found that the as-prepared surface could be varied from superhydrophilicity to superhydrophobicity just by controlling the drying temperature and the content Of SiO2 nanoparticles in the system. In addition, a transition from the Wenzel regime to the Cassie regime was observed. (C) 2007 Elsevier Inc. All rights reserved.
