Yanbin Cui, S. I. Kundalwal, S. Kumar

摘要:

由于其出色的电气,机械和热性能,石墨烯正在探索广泛的应用,并吸引了巨大的学术和工业兴趣。石墨烯及其衍生物也被认为是聚合物纳米复合材料(PNC)气体阻隔应用中有前途的纳米填料。本文综述了近年来石墨烯及其衍生物在不同聚合物基体纳米复合材料制备中的应用研究进展。介绍了石墨烯基纳米碳纤维的主要合成方法,包括溶液法、熔融法、原位聚合法和层层法。聚合物基质中的石墨烯层能够产生曲折的路径,其用作气体的屏障结构。高弯曲度导致PNC的更高阻隔性能和更低渗透性。这些填料(石墨烯及其衍生物)的固有特性和它们在聚合物基体中的分散状态对石墨烯/PNC的气体阻隔性能的影响进行了讨论。石墨烯/PNC的阻隔性能的分析建模方面也进行了详细的审查。我们还讨论和解决一些工作的混合基质膜的气体分离。

英文摘要:

Due to its exceptionally outstanding electrical, mechanical and thermal properties, graphene is being explored for a wide array of applications and has attracted enormous academic and industrial interest. Graphene and its derivatives have also been considered as promising nanoscale fillers in gas barrier application of polymer nanocomposites (PNCs). In this review, recent research and development of the utilization of graphene and its derivatives in the fabrication of nanocomposites with different polymer matrices for barrier application are explored. Most synthesis methods of graphene-based PNCs are covered, including solution and melt mixing, in situ polymerization and layer-by-layer process. Graphene layers in polymer matrix are able to produce a tortuous path which works as a barrier structure for gases. A high tortuosity leads to higher barrier properties and lower permeability of PNCs. The influence of the intrinsic properties of these fillers (graphene and its derivatives) and their state of dispersion in polymer matrix on the gas barrier properties of graphene/PNCs are discussed. Analytical modeling aspects of barrier performance of graphene/PNCs are also reviewed in detail. We also discuss and address some of the work on mixed matrix membranes for gas separation.
