| Abstract: | Nanometer sized CaCO3/SiO2 composite particles with core-shell structure were prepared by the
sol-precipitation process using sodium silicate and nanometer sized CaCO3 as precursors.The composite particles were organically in-situ hybridized by adding hybrophobicity inducing agent and silane coupling agents and the proterties are characterized.Their applications in silicone rubber matrix were studied. |
