氧化石墨烯对羧基丁腈橡胶/丁苯橡胶共混胶力学性能的影响:实验和分子模拟

Effect of graphene oxide on mechanical properties of carboxylated nitrile butadiene rubber/styrene-butadiene rubber blend:Experiment and molecular simulation

通过实验和分子模拟研究了氧化石墨烯(GO)对羧基丁腈橡胶(XNBR)和丁苯橡胶(SBR)共混胶力学性能的影响。结果表明,GO/XNBR/SBR体系存在大量氢键,且氢键总数和界面氢键数都随着XNBR含量的增加而增加;当添加75份(质量)XNBR时,GO/XNBR/SBR复合材料的拉伸强度比XNBR/SBR复合材料增加了86%,表明GO对XNBR/SBR共混胶具有增强作用,使得GO/XNBR/SBR体系的力学性能随着界面相互作用的增加而增强。

Rubber blending was an effective way to develop new rubber materials that could achieve better properties than those of single components.The properties of blend could be precisely controlled by using different types of rubbers.However,most blends tended to phase separation,which led to deterioration in mechanical properties.Graphene oxide(GO)could be used as a novel compatibilizer to improve compatibility between rubbers^([1-2]).
