Abstract
In-organic fillers are modified by in-situ co-polymerization of vinyl silane and another vinyl monomer. Vinyl silane couples with the filler by Si—O bonds. The remaining vinyl groups on the surface of the treated fillers then co-polymerize with the other vinyl monomer. The modified in-organic fillers treated by the in-situ co-polymerization are subsequently used to fill the polymer matrix. Tensile and impact strength of filler-reinforced polymer composites are improved remarkably.
