Abstract

The key to the preparation of polymer nanocomposites with new or improved properties resides in the homogeneous dispersion of the filler and in the efficient load transfer between components through strong filler/polymer interfacial interactions. This paper reports on the preparation of a series of nanocomposites of graphene and a polyolefin using different experimental approaches, with the final goal of obtaining multifunctional materials. A high-density polyethylene (HDPE) is employed as the matrix, while unmodified and chemically modified graphene fillers are used. By selecting the correct combination as well as the adequate preparation process, the nanocomposites display optimized thermal and mechanical properties, while also conferring good gas barrier properties and significant levels of electrical conductivity.

摘要

制备具有新的或改进性能的聚合物纳米复合材料的关键在于填料的均匀分散以及通过强大的填料/聚合物界面相互作用在各组分之间实现有效的载荷传递。本文报道了使用不同实验方法制备一系列石墨烯与聚烯烃的纳米复合材料，最终目标是获得多功能材料。采用高密度聚乙烯（HDPE）作为基体，同时使用未改性和化学改性的石墨烯填料。通过选择正确的组合以及适当的制备工艺，这些纳米复合材料展现出优化的热性能和机械性能，同时还具有良好的气体阻隔性能和显著的导电率。
