Abstract
A never route to form superhydrophobic-superhydrophilic micropatterned coat ing film has been developed. UV light was irradiated on the superhyrdrophob ic 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 ch ain in FAS selectively, and well-defined superhydrophobic and superhydrophi lic regions were formed.
