[资源] 先进的多功能的石墨烯气凝胶-聚酯（甲基丙烯酸甲酯）复合材料

Advanced multifunctional graphene aerogel Poly (methyl methacrylate) composites: Experiments and modeling，Carbon 81 (2015) 396-404. 影响因子：6.16
摘要：In 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 (0.160–0.859 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.
中文翻译摘要：在本研究中，通过将PMMA回填到GAs的孔中制备了石墨烯气凝胶（GA）-聚酯（甲基丙烯酸甲酯）（PMMA）复合材料，在PMMA基体中均匀分布多层的还原氧化石墨烯片（m-rGO）。通过二探针法，微压测试和红外比较方法测试了制备的GA-PMMA复合材料的电学、机械和热学性能。当石墨烯的载荷由0.67vol%增加到2.5vol%，复合材料的电导率（0.160-0.895S/m）、显微硬度（303.6-462.5MPa）和热导率（0.35-0.70W/mK）呈现显著的增加，用非晶格蒙特卡罗算法，考虑到复杂的形态、尺寸分布和m-rGO片分布，石墨烯和PMMA之间的热边界阻力是1.906×10-8m2K/W。想获得更多资源可点击链接http://www.tjdrfk.com/news/asedfrgbvc.html
