| Abstract: | Modified nanoscale silica sol was synthesized by one-step method at room temperature.The modified silica sol/polyacrylate nanocomposite emulsion was prepared by miniemulsion polymerization.The copolymer structure was characterized by FTIR.The influence of temperature on polymerization rate and monomer conversion was examined;the changes of latex particle size in the process of miniemulsion polymerization were monitored under different emulsifier content.The water absorption of the emulsion films was tested and the surface free energy of the emulsion films was characterized by contact angle analysis. |

| Keywords: | modified silica sol/polyacrylate nanocomposite emulsion miniemulsion polymerization monomer conversion surface free energy |
