摘要： An easy and effective method for fabricating a two layer structure of superhydrophobic inorganic/organic thin film with good mechanical property was developed by sol–gel process. The inorganic/organic thin film that is composed of SiO2 sol and polyvinyl butyral (PVB). The modified-SiO2 nanoparticles was effectively modified by methoxytrimethysilane and sprayed on an inorganic/organic (SiO2+PVB)-coated polycarbonate substrate. The water contact angle of the superhydrophobic inorganic/organic (SiO2+PVB) thin film was more than 150° and the average transmittance was 92.7% in the visible wavelength (400–700nm). According to ISO 2409 standard, the adhesion of the coated film has a quality of rank 1. The hardness was greater than 3H as performed by pencil hardness test. In addition, the superhydrophobic property was maintained after the thin film was treated by pressing wipe paper under a 500g weight and moving it parallel to the sample. The results demonstrate that the superhydrophobic inorganic/organic (SiO2+PVB) thin film has properties of superhydrophobicity, and good mechanical and optical properties. •Transparent superhydrophobic thin film with good mechanical properties•Water contact angle and transmittance of film are 158° and 92.7% (400–700nm).•Mechanical properties were effectively improved by using organic/inorganic layer. 出版者： Elsevier B.V 出版日期： 2016-11-01 出處： Thin solid films, 2016-11, Vol.618, p.219-223 版權： 2016 Elsevier B.V. 識別號： ISSN: 0040-6090 識別號： EISSN: 1879-2731 識別號： DOI: 10.1016/j.tsf.2016.02.034
