首次报道了氧化石墨烯(G-O)/聚合物复合材料的表面能和阻尼性能。采用溶液共混和二辊混炼相结合的方法制备了G-O/三元乙丙橡胶(EPDM)/石油树脂(PR)复合材料。扫描电子显微镜结果表明，G-O纳米片材在三元乙丙橡胶和三元乙丙橡胶/PR共混物中分散均匀。这种良好的分散性初步归因于通过接触角测试确定的三元乙丙橡胶和G-O的匹配表面能和较低的界面能。加入0.5wt%的G-O纳米片材后，三元乙丙橡胶的拉伸模量、拉伸强度和断裂伸长率分别提高了130%、50%和30%以上。含有复合材料的G-O纳米片材在改善三元乙丙橡胶(/PR)的减振性能方面是一种新颖的方法。热重分析表明，G-O对三元乙丙橡胶(/PR)的热稳定性影响不大。
The surface energy and damping properties of graphene oxide (G-O)/polymer composites were reported for the first time. G-O/ethylene-propylene-diene rubber (EPDM)/petroleum resin (PR) composites were prepared by the combination of solution-blending and two-roll mill mixing. SEM results demonstrate that G-O nanosheets were dispersed homogeneously in EPDM and EPDM/PR blends. Such good dispersion was preliminarily attributed to the matched surface energy as well as low interfacial energy of EPDM and G-O, which were determined by contact angle tests. The addition of 0.5 wt% G-O nanosheets increased the tensile modulus, tensile strength and elongation at the break of EPDM by more than 130%, 50% and 30%, respectively. G-O nanosheets containing composites were novel in improving the damping properties of EPDM(/PR). The thermogravimetric analysis tests show that G-O slightly changed the thermal stability of EPDM(/PR).
