The invention provides a composition used for material surface treatment, and a material with hydrophobic surface and a hydrophobic film which are prepared with the composition. The material surface treatment composition comprises wax, silicon oil, hydrocarbon mixture oil from C6 to C30, nano powder and resin; making use of the nano-powder of the composition, the modified material surface can be endowed with the property of low detention resistance against water caused by low surface energy and coarseness.
