Abstract
Frictional and wear properties of polyamide 6 (PA6) are very important for its use as anengineering plastic. 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.
