聚苯乙烯光子晶体薄膜的光化学行为
Photochemical Behavior of Polystyrene Photonic Crystals Film
摘要
Abstract
The morphology, optical properties and wettability of polystyrene (PS) photonic crystals (PC) films were studied under UV irradiation. The hydrophilic carbonyl group formed on the surface of PS microsphere after UV irradiation, which was demonstrated by characterizing the chemical composition of the surface using FTIR. Scanning electron microscopic images show that the PS sphere would contract, deform and melt compa-nying with longer time of UV irradiation. The in situ reflectance and transmittance spectra indicated that the PC film could preserve good optical properties and changed from hydrophobic to hydrophilic in 20 min of UV irradiation. Therefore, the hydrophilic polymer PC film with good optical properties can be obtained by controlling the UV irradiation time, which will be of great importance for the application of PC in the special system.关键词
