Study on the fabrication and tribological behavior of self-assembled functionalized graphene oxide in water

A new lubricating coating with functionalized graphene oxide (fGO) consisting of (GO) different oxidation degrees, n-octylamine basal plane GO (bGO), and edge (eGO) was developed or without 3-aminopropyltrimethoxysilane (APTMS) to reduce friction in macroscale contact water. The optimal preparation condition the obtained by single factor evaluation a series factors (20 % APTMS aqueous solution, 12 h immersion time, 0.05 mg/mL 100 °C curing temperature). effect degree functionalization on friction-reducing anti-wear behavior explored. coatings higher exhibited better friction-reduction performance. In addition, capability APTMS-bGO greater than that APTMS-eGO.
