Silica-chitosan hybrid films were made of tetraethylorthosilicate (TEOS) as a precursor and chitosan, using sol–gel method. The films were characterized by water contact angle (WCA) measurements, Brunauer Emmett Teller (BET), scanning electron microscope (SEM) for wettability, surface, cross section morphology and specific surface area, respectively. Also, it is confirmed that hydrogen bonds emerge between chitosan and SiO2 in hybrid materials by Fourier transform infrared (FT-IR) analysis
