分别通过超声共混法和原位还原法制备了石墨烯/环氧树脂复合材料.利用X射线光电子能谱(XPS)、X射线衍射(XRD)、光学显微镜和扫描电子显微镜(SEM)对复合材料的结构进行了表征,并对其力学性能进行了测试.结果表明,原位还原法制备的石墨烯/环氧树脂复合材料中,氧化石墨烯已经被成功地还原为石墨烯,并且石墨烯具有良好的分散性.力学性能测试结果表明,两种方法制备的复合材料的力学强度较纯环氧树脂明显提高.当石墨烯的量为m(GO)/m (EP)=0.3/100时,超声混合法制备的石墨烯/环氧树脂复合材料的拉伸强度和弯曲强度分别最大提高约29.2%和1.4%;而原位还原法制备的石墨烯/环氧树脂复合材料的拉伸强度和弯曲强度分别最大提高约40.5%和9.4%.
