Abstract Flexible dielectric chloroprene rubber (CR) nanocomposites reinforced by one-dimensional carbon nanotube (CNT)/two dimensional reduced graphene oxide hybrids have been prepared using two-roll mill mixing technique. Non-covalent π-π interaction between multiwalled carbon nanotubes (MWCNTs) and reduced graphene oxide (RGO) nanosheets and the secondary interaction between fillers and chloroprene rubber matrix are responsible for generating the effective load transfer between RGO/MWCNTs and CR. The prepared RGO-MWCNT hybrid nanocomposites with high dielectric constant (≈650), low dielectric loss (≈0.42) and high energy storage efficiency (78.6%) values are practically good enough to use as a low cost polymeric dielectric layer in transistors. Furthermore, the prepared nanocomposites showed excellent electromagnetic effectiveness; a maximum shielding efficiency of 11.87 dB @ 3.5 GHz was achieved at 4 phr of MWCNT loading. This excellent electromechanical performance can be ascribed to the synergistic effect of RGO-MWCNT hybrid suggesting that this novel hybrid nanocomposite serves as an attractive candidate in modern electronics and electric power systems.

RGO/MWCNT杂化填料增强聚氯丁橡胶多功能纳米复合材料影响的综合研究

摘要 使用两辊磨混合技术制备了一维碳纳米管（CNT）/二维还原氧化石墨烯杂化物增强的柔性介电氯丁橡胶（CR）纳米复合材料。多壁碳纳米管 (MWCNTs) 和还原氧化石墨烯 (RGO) 纳米片之间的非共价 π-π 相互作用以及填料和氯丁橡胶基质之间的二次相互作用负责在 RGO/MWCNTs 和 CR 之间产生有效的负载转移。制备的 RGO-MWCNT 混合纳米复合材料具有高介电常数 (≈650)、低介电损耗 (≈0.42) 和高储能效率 (78.6%) 值，实际上足以用作晶体管中的低成本聚合物介电层。此外，所制备的纳米复合材料表现出优异的电磁效应；在 4 phr MWCNT 负载下实现了 11.87 dB @ 3.5 GHz 的最大屏蔽效率。这种优异的机电性能可归因于 RGO-MWCNT 混合材料的协同效应，表明这种新型混合纳米复合材料在现代电子和电力系统中是一种有吸引力的候选材料。
