摘要
为提高环氧树脂的导电性能和电磁屏蔽性能,将石墨烯作为导电填料添加到环氧树脂中制备了环氧树脂/石墨烯复合材料,并研究了石墨烯含量对复合材料力学性能及微观形貌的影响.结果表明:添加石墨烯使复合材料的电导率和电磁屏蔽效率显著提高.石墨烯含量为10.0%(w)时,复合材料的电导率和电磁屏蔽效率分别为1.34×10-3 S/m,2.95 dB;石墨烯含量为7.5%(w)时,复合材料的冲击强度为1.67 kJ/m2,较纯环氧树脂提高了50%.
Abstract
Graphene employed as conductive fillers were added to epoxy resin to enhance the electrical conductivity and electromagnetic shielding efficiency of epoxy resin.The influence of graphene content on mechanical properties and microstructure of the composites were investigated.The results show that the electrical conductivity and electromagnetic shielding efficiency of the composites are significantly improved by adding graphene.The electrical conductivity and shielding of the composites are 1.34×10-3 S/m and 2.95 dB when the mass fraction of graphene is 10.0%;the impact strength of the composites is 1.67 kJ/m2 when the mass fraction of graphene is 7.5%,which is higher than that of pristine epoxy resin by 50%.
