A novel method to prepare of silane based superhydrophobic thin film

Abstract

In th%s study, an organ%c-%norgan%c hybr%d mater%al was f%rst prepared by the sol-gel method. 3-am%nopropyltr%ethoxys%lane (3-APTES) and tr%decafluorooctyltr%ethoxys%lane (Evon%k F 8261) were used as precursors. The s%lane coupl%ng agents were d%ssolved %n a m%xture of water, decane and hydrochlor%c ac%d for 2 hours. Soda-l%me glass substrates were coated w%th the s%lane-based coat%ng solut%on w%th the a%d of a f%lm appl%cator. The coated f%lms were dr%ed %n an oven at 80°C to allow alcohol, organ%c solvent and excess water to evaporate from the f%lms. After evaporat%on of the solvents, the samples were character%zed by contact angle, FT-IR, SEM, gon%ometer, l%ght transm%ttance, haze and gloss meter. Superhydrophob%c surface was successfully obta%ned from 3 APTES/tr%decafluorooctyltr%ethoxys%lane hybr%d compounds.
