Advanced multifunctional graphene aerogel Poly (methyl methacrylate) composites: Experiments and modeling£¬Carbon 81 (2015) 396-404. Ó°ÏìÒò×Ó£º6.16 ÕªÒª£ºIn this work, graphene aerogel (GA) poly (methyl methacrylate) (PMMA) composites are first developed by backfilling PMMA into the pores of the GAs, providing uniform distribution of multi layer reduced graphene oxide (m rGO) sheets in the PMMA matrix. Electrical, mechanical and thermal properties of the as prepared GA PMMA composites are investigated by two probe, microindentation and comparative infrared techniques respectively. As graphene loadings increase from 0.67 to 2.50 vol.%, the composites exhibit significant increases in electrical conductivity (0.160¨C0.859 S/m), microhardness (303.6 to462.5 MPa) and thermal conductivity (0.35to 0.70W/mK) from that of pure PMMA as well as graphene PMMA composites prepared by traditional dispersion methods. Thermal boundary resistance between graphene and PMMA is estimated to be 1.906. 108m2 K/W by an off lattice Monte Carlo algorithmthat takes into account the complexmorphology, size distribution and dispersion of m rGO sheets.
