Nanotechnology has been explored recently as a means of enhancing the properties of conventional elastomers for engineering applications. In the current study, the effect of nanofillers on air impermeability properties of Brominated isobutylene‐isoprene rubber (BIIR)/Epoxidized natural rubber (ENR) blend has analyzed for automotive applications. The ENR chosen is ENR 25 and ENR 50 (25 and 50% epoxidation) and prepared the blends in a ratio of 75:25 (BIIR:ENR), and from both blend based composites, a part of carbon black replaced with graphene nanoplatelets (GNP). The physical and thermal properties were compared for both binary blend nanocomposites to study the level of exfoliation and reinforcement behavior of GNP. Morphology studies were employed to reveal the level of interaction between GNP and carbon black in both blends. The influence of epoxidation in the formation of nanostructures in both blends have been evaluated, and the effect of nanostructures on air permeability properties was studied. The air impermeability of BIIR‐ENR 50 nanocomposites were improved with increasing platelet concentration, a 30% improvement in air permeability is obtained for BIIR‐ENR 50 composites over BIIR ‐ENR 25.

炭黑与石墨烯纳米片在用于内衬的溴化丁基橡胶/环氧化天然橡胶复合材料中杂交的透气性评估

近年来，已经探索出纳米技术作为增强常规弹性体用于工程应用的性能的手段。在当前的研究中，已针对汽车应用分析了纳米填料对溴化异丁烯-异戊二烯橡胶（BIIR）/环氧天然橡胶（ENR）共混物的不透空气性的影响。选择的ENR为ENR 25和ENR 50（25和50％环氧化），并以75:25（BIIR：ENR）的比例制备共混物，并从两种共混物基复合材料中，一部分碳黑被石墨烯纳米片代替（ GNP）。比较了两种二元共混纳米复合材料的物理和热学性质，以研究GNP的剥落和增强行为。形态学研究用于揭示两种混合物中GNP和炭黑之间的相互作用水平。评价了两种共混物中环氧化对纳米结构形成的影响，并研究了纳米结构对透气性的影响。随着血小板浓度的增加，BIIR‐ENR 50纳米复合材料的透气性得到改善，与BIIR‐ENR 25相比，BIIR‐ENR 50复合材料的透气性提高了30％。
