石墨烯/橡胶导电纳米复合材料的研究进展

摘要

The conductive mechanism of graphene/rubber nanocomposites was introduced.Advances in the synthesis and properties of graphene and its derivatives,modifications of graphene,along with its hybrid fillers,as well as fabrication of related rubber conducting nanocomposites were reviewed.Many factors affecting the electrical properties,such as fabrication method,vulcanization,temperature,pressure,frequency and media etc.were also summarized.It was pointed out that the further research should be focused on multi-component graphene/rubber nanocomposites and its double percolation phenomenon.%介绍了石墨烯/橡胶纳米复合材料的导电机理,综述了石墨烯及其衍生物、石墨烯的处理改性、与其他材料共混以及纳米导电复合材料的制备,论述了加工方法、硫化工艺以及温度、压力、频率、介质等因素对石墨烯/橡胶纳米复合材料导电性能的影响,并指出多组分橡胶/石墨烯复合体系及其“双逾渗”行为等都将是未来导电石墨烯/橡胶研究的重点.
