▎ 摘　　要

NOVELTY - A super water-skiing lubricant additive has a hollow spherical shell structure including a spherical shell layer, which sequentially comprises from inside to outside, a polydopamine layer (A), a nanoparticle layer, a polydopamine layer (B), a graphene oxide layer and a polydopamine layer (C). The nanoparticles of the nanoparticle layer are nanodiamonds, nano-molybdenum disulfide or nano-tungsten disulfide. USE - The super water-skiing lubricant additive is useful in super water-skiing lubricant for mechanical moving component or biological lubrication (all claimed). ADVANTAGE - The super water-skiing lubricant additive is easy to absorb on the coupling surface. The nanoparticles released during the friction process can be cooperated with the spherical graphene oxide or graphene to form rolling friction, thus reducing friction and wear resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the super water-skiing lubricant additive, which involves preparing the polydopamine layer (A) on a surface of spherical nano metal oxide, connecting the surface of the polydopamine layer (A) to nanoparticles, loading the surface of the polydopamine layer (A) with the nanoparticle layer, then preparing the polydopamine layer (B) on the surface of the nanoparticle layer, bonding the surface of the polydopamine layer (B) to the graphene oxide surface groups through hydroxy group or pi - pi bonds, so that graphene oxide forms a graphene oxide layer on the surface of the polydopamine layer (B), and using an acid solution to etch and remove nano metal oxide, or preparing the polydopamine layer (A) on the surface of the spherical nano metal oxide, connecting the surface of the polydopamine layer (A) to nanoparticles, loading the surface of the polydopamine layer (A) with the nanoparticle layer, then preparing the polydopamine layer (B) on the surface of the nanoparticle layer, bonding the surface of the polydopamine layer (B) to the graphene oxide surface groups through hydroxy group or pi - pi bonds, so that graphene oxide forms a graphene oxide layer on the surface of the polydopamine layer (B), using dopamine to prepare the polydopamine layer (C) on the surface of the graphene oxide layer, when preparing the polydopamine layer (C), using dopamine to reduces graphene oxide to graphene, and using an acid solution to etch and remove nano metal oxide; and (2) a super water-skiing lubricant.
