Abstract
A novel route to form superhydrophobic−superhydrophilic micropatterned coating film has been developed. UV light was irradiated on the superhydrophobic coating film which consists of three layers, a flowerlike Al2O3 gel film, a very thin TiO2 gel layer, and a FAS layer, to cleave the fluoroalkyl chain in FAS selectively, and well-defined superhydrophobic and superhydrophilic regions were formed.
