Fabrication and Characterization for Innate Super-hydrophilic SiO2 Thin Films

摘要：

　　Distinguished with photoinduced super-hydrophilic inorganic thin films,non-photoinduced innate super-hydrophilic SiO2 thin films were successfully fabricated in this work.The SiO2 sol was prepared by acid-base two-step sol-gel method.The mix solution containing SiO2 sol and polyethylene glycol (PEG) was coated on glass substrate and then went through thermal treatment to obtain innate super-hydrophilic SiO2 thin films.The films were characterized by atomic force microscopy (AFM),scanning electron microscopy (SEM),Fourier transform infrared spectroscopy (FT-IR) and contact angle meter.The results show that the surface concave-convex microstructure and the hydroxyl content are the factors that endow the SiO2 coating films with innate super-hydrophilic property.
