| Abstract: | The surface of the nano-calcium carbonate was modified with KH-570,the polymethyl methacrylate(PMMA)/ CaCO3 nanocomposites were prepared by in situ polymerization.The interfacial compatibility between nano-CaCO3 and PMMA matrix was characterized by dissolution,scanning electron microscope(SEM),Fourier transform infrared spectrum(FT-IR),the mechanical property of nanocomposites was studied.The results show that nano-CaCO3 may be crosslinking points in the matrix.There are good dispersion and interfacial adhesion between the modified nano-CaCO3 and the PMMA matrix.As the content of nano-CaCO3 increases to 1%,its tensile strength increases by about 35%,impact strength increases by about 70%,flexural strength increases by about 60%. |
