| Abstract: | Graphene oxide was prepared by improving Hummers method and then modified by 4,4′-oxydianiline to get aminated graphene oxide, which was used to construct redox initiator system with dibenzoyl peroxide for synthesis of poly(methyl methacrylate) grafted to graphene oxide by in situ polymerization. Nanocomposites used grafted polymer as fillers with loadings from 0.5 to 1.0 wt % of poly(methyl methacrylate) were obtained by solution blending. The structures, properties and morphology of graphene oxide, grafted poly(methyl methacrylate) and composites are characterized by Fourier transform infrared spectroscopy, X-ray diffraction, Raman spectra, scanning electron microscopy, thermogravimetric analysis, dynamic mechanical thermal analysis and bacterial adhesion examination respectively. The initial decomposition temperature and the glass transition temperature of the nanocomposites are improved by addition of grafted poly(methyl methacrylate). Furthermore, there is a significant enhancement of the decreasing of the surface bacterial adhesion of prepared nanocomposites. |
