| Abstract: | PP/nano-SiO2 composites were prepared by melt-blending process.The effect of PP-g-MAH on mechanic properties,crystallization properties and interfacial interaction of composites were studied.The results showed that:PP-g-MAH enhances the interfacial interaction between nano-SiO2 and PP matrix,and improves the mechanic properties of the composites;meanwhile,PP-g-MAH enhances the nucleating activity of nano-SiO2,which makes the crystallization temperature of PP increase,and the spherulite of PP become finer. |
