Characterization of anti-reflective and self-cleaning SiO2-TiO2 composite film

摘要

Sol-gel dip-coating technique can be used to fabricate SiO2-TiO2 composite film with self-cleaning and anti-reflectance properties from low-cost SiO2 colloid solution and Ti(OC4H9)4. The physical and structural properties have been investigated by UV-visible spectrophotometer, contact angle meter, XRD, FT-IR, FESEM. UV-vis spectra and methyl orange photodegradation experiments showed that the SiO2-TiO2 composite film had high light transmittance and photocatalytic activity.
