In this paper, graphene was synthesized on sapphire substrate by chemical vapor deposition (CVD) method, and the effect of growth time on hydrophobic properties and microstructure of graphene was investigated. Contact-angle meter, Fourier transform infrared spectrometer, Raman spectrometer and field emission scanning electron microscopy were applied to study hydrophobic and microscopic structure of graphene, respectively. It shows that after growing 30 min, maximum contact angle of graphene is 129.96°, it presents hydrophobic properties. Meantime, infrared test shows only carbon-carbon double bonds. Raman analysis also indicates three characteristic peaks of graphene after growing 10-30 min. larger contact angle makes graphene as a potential hydrophobic material, and it can even be a promising superhydrophobic material by its hydrophobic modification.
