Abstract Frictional and wear properties of polyamide 6 (PA6) are very important for its use as a engineering plastics. In this study, octaamino-polyhedral oligomeric silsesquioxane (POSS) functionalized graphene oxide (GO) was used to fabricate a PA6/reduced GO-POSS (rGO-POSS) nanocomposites. Compared with PA6, the PA6/rGO-POSS nanocomposites with 0.3 wt% GO-POSS has a decrease of friction coefficient by 86.36% from 0.44 to 0.06. The depth and width of the wear scar were reduced by 79.64% and 70.69%, respectively. Meanwhile, the wear rate reached the lowest and dropped by about 65.72%. The research found that GO-POSS is self-fixed in the matrix and effectively increases the interface bonding strength.

具有多个反应位点的 POSS 功能化氧化石墨烯纳米片改善了聚酰胺 6 的摩擦磨损性能

摘要 聚酰胺 6 (PA6) 的摩擦磨损性能对其作为工程塑料的使用非常重要。在这项研究中，八氨基-多面体低聚倍半硅氧烷 (POSS) 功能化氧化石墨烯 (GO) 用于制造 PA6/还原 GO-POSS (rGO-POSS) 纳米复合材料。与 PA6 相比，含有 0.3 wt% GO-POSS 的 PA6/rGO-POSS 纳米复合材料的摩擦系数从 0.44 降至 0.06，降低了 86.36%。磨痕的深度和宽度分别减少了 79.64% 和 70.69%。同时，磨损率达到最低，下降了约65.72%。研究发现GO-POSS在基体中自固定，有效增加界面结合强度。
