ABSTRACT

Graphene (G) was produced and melt-blended with polyamide 6 (PA6) to study the mechanical, electrical, and flame-hindrance characteristics of PA6-G compounds. It resulted that G is well dispersed in PA6 up to 2.0 wt% owing to electrostatic contact. A clear increment in degradation temperature and a drop in extreme degradation degree is detected from the thermogravimetric experiment for PA6-G compounds. The G inclusion to PA6 amended flame-protection of PA6-G compounds by delaying smoke density and reduction of flammable gas. This work proved an appropriate formulation of polymer/G compounds applied to engineering materials; develop the types of compounds with nano-additives.

摘要

生产石墨烯 (G) 并将其与聚酰胺 6 (PA6) 熔融共混，以研究 PA6-G 化合物的机械、电气和阻燃特性。结果表明，由于静电接触，G 在 PA6 中的分散量高达 2.0 wt%。从 PA6-G 化合物的热重实验中检测到降解温度明显增加，极端降解程度下降。在 PA6 中加入 G 通过延缓烟雾密度和减少可燃气体来改善 PA6-G 化合物的阻燃性。这项工作证明了适用于工程材料的聚合物/G 化合物的适当配方；开发具有纳米添加剂的化合物类型。
