▎ 摘　　要

A super-hydrophobic graphene oxide (GO)-azobenzene (Azo) hybrid material was synthesized through a covalent grafting of amide linkage. Fourier transforms infrared spectra (FTIR) and UV-visible (UV-vis) spectra confirmed the successful formation of GO-Azo hybrid material. The GO-Azo exhibited high water repellence with water contact angle of similar to 152 degrees. As a new kind of filler material, the scope GO-Azo in improving the hydrophobicity of polyurethane was investigated through contact angle measurements of polyurethane films with varying amount of GO-Azo. Mechanical and thermal studies showed improved stability and rigidity of the composite film as well at doping ratio of only 3 wt% the of the filler.
