离子液体改性氧化石墨烯对丁苯橡胶热性能的影响

摘要本文利用氯化1-烯丙基-3-甲基咪唑（AMICl）将氧化石墨烯（GO）表面处理，再通过乳液混合法把GO（GO-IL）与丁苯橡胶（SBR）混合制取GO-IL/SBR。探索研究AMICl与GO之间作用机理和GO-IL的填充量及表面处理对SBR的耐热性、热传导能力和动态力学性能（DMA）等的影响。结果表明：氢键和π-阳离子作用为AMICl和GO之间的主要界面作用。同时GO-IL的填充能够改善SBR胶料的耐热性能、热传导能力和交联密度等。GO-IL5/SBR与未填充SBR作比较，其材料分解速率最大时的温度（Tmax）提高19。9℃，热传导系数提升34%，交联密度提高了98。7%。73662

Title The influence of ILs modified graphene oxide on the thermal properties of styrene-butadiene rubber composites

Abstract In this study, graphene oxide (GO) was surface-modified by Ionic liquid 1-allyl-3-methyl-imidazolium chloride (AMICl), and then the AMICl modified GO/styrene-butadiene rubber (GO-IL/SBR) nanocomposites were fabricated by mixing GO-IL suspension with SBR latex。 The interaction between GO and AMICl molecules as well as the effects of GO-IL on the thermal stability, thermal conductivity and DMA of GO-IL/SBR nanocomposites were investigated。 It is found that AMICl molecules can interact with GO via the combination of hydrogen bond and cation-π interaction and the thermal stability, thermal conductivity and crosslinking density of GO-IL/SBR nanocomposites were improved with the addition of AMICl。 The GO-IL5 nanocomposites have the best properties that the thermal conductivity had a 34% increment, the temperature at maximum decomposition rate of sample (Tmax) was improved by 19。9℃。 Moreover, the crosslinking density was increased by 98。7%, compared with neat SBR。
