Interfacial interaction is one of the most crucial and dominant factors affecting the performance and behavior of a material. The surfaces of layered expanded graphite (EG) were activated by covalently grafted mercapto groups (-SH), which can readily react with the macromolecular chains of rubber, thus forming a strong interfacial adhesion between the filler and the rubber matrix. Shear-induced mercapto-group-activated graphite nanoplatelets ([email protected]) were fabricated in situ by compound mixing in a two-roll mill. A correlation between the interfacial interaction and the thermal conductivity, as well as the thermo-physical properties, was comprehensively investigated. The results showed that rubber/[email protected] composites exhibited better mechanical performance, enhanced thermo-physical properties, and superior thermal conductivity, all of which could be attributed to the stronger interfacial interaction resulting from chemical bonding between the [email protected] and the molecular chains of the rubber, relative to XSBR/GNP composites connected by weaker π-π stacking.

界面相互作用是影响材料性能和行为的最关键和最主要的因素之一。层状膨胀石墨（EG）的表面被共价接枝的巯基（-SH）活化，该基团易于与橡胶的大分子链反应，从而在填料和橡胶基体之间形成牢固的界面粘合力。剪切诱导的巯基活化石墨纳米片（[电子邮件保护]）原位制备。在两辊磨机中混合混合。全面研究了界面相互作用与热导率以及热物理性质之间的关系。结果表明，橡胶/ [受电子邮件保护的]复合材料表现出更好的机械性能，增强的热物理性能和优异的导热性，所有这些都可以归因于[受电子邮件保护的]和[受电子邮件保护的]之间的化学键合。相对于通过较弱的π-π堆叠连接的XSBR / GNP复合材料而言，橡胶的分子链。
