Natural rubber (NR)/carbon nanotube (CNT) composites containing ionic liquid (IL) at different concentrations have been prepared by using an internal mixer in the conventional mechanical mixing method. The role of a green solvent IL 1-butyl-3-methyl imidazolium chloride (BMIC) on the curing kinetics, mechanical, morphological and thermal properties of NR–CNT composites has been studied. It has been found that BMIC strongly influenced rheometric data and mechanical properties. The addition of the IL (1-ethyl-3-mehylimidazolium chloride) significantly increased the vulcanization rate, decreased scorch and cure times. The plasticizing effect of IL on the composite is well understood from the results of different analysis. The increment in the free volume of the nanocomposites by the effect of IL was studied using positron annihilation lifetime spectroscopy. The mechanical properties such as tensile strength and elongation at break increased with small amount of IL. With high amount...

咪唑鎓离子液体对天然橡胶/碳纳米管复合材料性能的加速固化和增塑作用

通过使用常规机械混合方法中的内部混合器已经制备了包含不同浓度的离子液体（IL）的天然橡胶（NR）/碳纳米管（CNT）复合材料。研究了绿色溶剂IL 1-丁基-3-甲基咪唑鎓氯化物（BMIC）对NR-CNT复合材料的固化动力学，机械，形态和热性能的影响。已经发现，BMIC强烈影响流变数据和机械性能。IL（1-乙基-3-甲基咪唑鎓氯化物）的添加显着提高了硫化速率，减少了焦烧和固化时间。从不同分析的结果中可以很好地了解IL对复合材料的增塑作用。使用正电子an没寿命光谱研究了通过IL的影响，纳米复合材料的自由体积的增加。少量的IL会提高机械性能，例如拉伸强度和断裂伸长率。大量...
