Graphene and its derivatives have received considerable attention in industrial and academic research due to their unique, useful properties and applications. The use of graphene is still difficult due to its high cost of production. Hence, graphene nanoplatelets (GNPs) have been identified as a substitute for graphene, which are produced in large scale at a very low cost. Moreover, GNPs have played a significant role in various engineering thermoplastic materials [i.e., polyamides (PAs)] to enhance their properties and applications. The GNPs help in the production of low-cost multifunctional nanocomposites with notable useful properties such as high electrical conductivity, mechanical strength, and high aspect ratio. The GNPs based nanocomposites have a broad spectrum of application areas including 3D-printing, automotive materials, electrical appliances, low-cost composites films, and many more. This review summarizes different preparation techniques, properties, and applications of GNPs based PAs nanocomposites as reported in current literature.

石墨烯及其衍生物由于其独特，有用的性质和应用而在工业和学术研究中引起了相当大的关注。由于其高生产成本，石墨烯的使用仍然困难。因此，石墨烯纳米片（GNP）已被确定为石墨烯的替代品，石墨烯以非常低的成本大规模生产。此外，GNP在各种工程热塑性材料[即聚酰胺（PA）]中发挥了重要作用，以增强其性能和应用。GNP有助于生产低成本的多功能纳米复合材料，这些复合材料具有显着的有用特性，例如高电导率，机械强度和高长宽比。基于GNP的纳米复合材料具有广泛的应用领域，包括3D打印，汽车材料，电器，低成本复合膜等。这篇综述总结了目前文献中报道的基于GNPs的PAs纳米复合材料的不同制备技术，特性和应用。
