Graphene addition to low-density polyethylene prolonged oxygen penetration in low-density polyethylene (LDPE), deferred embrittlement effect of polymeric compound, developed storage modulus, electrical conductivity and enhanced viscosity of LDPE nanocompounds. The presence of graphenes inhibited movement of polymer chains, which affected increasing toughness and capability of LDPE compounds. Continuity of carbon–carbon connection threshold of graphene compound took place with about 0.5 wt% graphene inclusion in LDPE structure. The impenetrability of oxygen over the surface of LDPE compounds achieved with 0.5 wt% graphene inclusion, which made severe perfections and decreased 37% fuel penetration if it is compared to pristine LDPE.

石墨烯对 LDPE 特性的影响

在低密度聚乙烯中添加石墨烯延长了低密度聚乙烯 (LDPE) 中的氧渗透，延缓了聚合物的脆化效应，提高了低密度聚乙烯纳米化合物的储能模量、导电性和粘度。石墨烯的存在抑制了聚合物链的运动，从而影响了 LDPE 化合物的韧性和性能的增加。石墨烯化合物的碳-碳连接阈值的连续性发生在 LDPE 结构中包含约 0.5 wt% 的石墨烯。氧气在 LDPE 化合物表面上的不可渗透性是通过包含 0.5% 的石墨烯实现的，如果与原始 LDPE 相比，这使得它非常完美并降低了 37% 的燃料渗透。
