Using friction coefficient tester, we have investigated the humility and UV-light dependence of the adhesive force and friction coefficient on glass surface and nano-TiO 2 film coated glass surfaces in the relative humidity of 30%～70%. The results show that nano-TiO 2 film can improve the frictional characteristics of glass, UV-light can enhance the hydrophilicity of the sample surfaces. we also find that, due to the water vapor condensation, the adhesive force and friction coefficient on sample surfaces increase first, then decrease with the relative humidity increase.
