J Colloid Interface Sci:石墨烯改良高性能橡胶复合材料

2019-05-10 不详 网络

通过掺入通过常规方法获得的石墨烯,同时改善橡胶复合材料的耐老化性,机械强度,导热性和介电常数仍然是一个挑战。在此,研究人员提出了一种有效的绿色方法,通过一锅法用2-巯基苯并咪唑(抗氧化剂MB)同时还原和功能化氧化石墨烯(GO)。 结果显示,GO成功被MB还原,且在GO表面进行了化学修饰(G-MB)。G-MB片均匀分散在橡胶中,具有强的界面相互作用,石墨烯-石墨烯导电通路通过接枝的抗氧化剂分子之间的

通过掺入通过常规方法获得的石墨烯,同时改善橡胶复合材料的耐老化性,机械强度,导热性和介电常数仍然是一个挑战。在此,研究人员提出了一种有效的绿色方法,通过一锅法用2-巯基苯并咪唑(抗氧化剂MB)同时还原和功能化氧化石墨烯(GO)。

结果显示,GO成功被MB还原,且在GO表面进行了化学修饰(G-MB)。G-MB片均匀分散在橡胶中,具有强的界面相互作用,石墨烯-石墨烯导电通路通过接枝的抗氧化剂分子之间的分子间H键形成。因此,具有G-MB的橡胶复合材料显示出比具有水合肼的橡胶复合材料降低的GO(rGO)更高的导热性,机械强度和介电常数。此外,由于消除了接枝MB分子的起霜效应,具有G-MB的橡胶复合材料的热氧化老化性也优于具有rGO的橡胶复合材料。

因此,这项工作可能为GO的环保功能化和还原开辟了一条新途径,并可能促进高性能,功能性石墨烯-弹性体复合材料的发展。
