Fabrication and Characterization of Polyorganosiloxane Superhydrophobic Film by Sol-Gel Method

Abstract:

The polyorganosiloxane superhydrophobic film was fabricated via a sol-gel process followed by nano-silica(SiO₂) sol and new organo-siloxane reagent 1,1,1,3,5,5,5-heptamethyl-3-[2-(trimethoxysilyl)-ethyl]-tri-siloxane(in brief as HPTETOs), the chemical structure of the polyorganosiloxane superhydrophobic were described by Fourier transform infrared spectroscopy (FT-IR), the superhydrophobic property of the treated sample was measured by contact angle (CA) measurements. It revealed that nano-silica and polyorganosiloxane formed 3D hydrophobic groups on the film; the film has turned its wetting property from hydrophilic to superhydrophobic with water contact angle of 143.7°.
