The composite material nano-BMC/γ-MPS/PMMA was prepared using nano-BMC as raw material, which was obtained by brine method. The nano-BMC whisker was pretreated by silane coupling agent 3-(trimethoxysilyl) propyl methacrylate (γ-MPS) and then conducted to surface radical grafting polymerization which is initiated by water-soluble initiator K2S2O8 in ethanol/water mixture. The structure and morphology of nano-BMC/γ-MPS/PMMA was characterized by Fourier Transformed Infrared Spectroscope (FT-IR), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) analysis. The influences of reaction conditions on the conservation of whisker morphology and grafting polymerization were investigated. The result shows that the reaction conditions have a significant effect on the morphology of nano-BMC whisker. The grafting efficiency reaches 56.1% and the morphology of nano-BMC whisker is well conserved when the reaction is kept at 82℃ for 6h in the ethanol-water solution with the 8∶2 ratio of ethanol to water.
