摘要

An investigation into Poly (methyl methacrylate) (PMMA) grafted onto nano-SiC particles is reported in this study. In our experiment, the grafting polymerization reaction is induced by radio frequency (RF) discharge of N2 plasma treatment of the nanosized powder. FTIR (Fourier transform infrared spectrum), XPS (X-ray photoelectron spectroscopy) and TGA (Thermogravimetric analysis) results reveal that PMMA is grafted onto the surface of silicon carbide powder, and the crystal structure of the silicon carbide powder observed with XRD (X-ray diffraction) spectra is unchanged before and after the plasma graft polymerization.
