Abstract: The complex membranes with antistatic property made by SiO2 wrapped nanopowder and polyacrylate emulsifier solution through coating. TEM photos showed that SiO2 wrapped are balls and the even dispersion in the units with several particles that the average diameters of SiO2 wrapped are 20nm,the sizes of units are smaller than 100nm. The results by the preparation of the complex membrane with antistatic property were that the surface resistance rate of the complex membrane was 108Ω/cm when SiO2 wrapped nanopowder weight percent was 22% and the complex membrane with antistatic property was half transparent membrane. The surface of the complex membrane with antistatic property had a certain of hydrophilic property and its surface resistance rate was 106Ω/cm after drying under 20～30℃ and 60%～80% air humidity after 2～4h.
