Latest Patents

Liu is named on 1 patent: “Ultra-high molecular weight polyethylene anti-wear composite material modified by manganese phosphate nanosheet and preparation method thereof.” The invention describes mechanically mixing trihydrate manganese phosphate nanosheets with UHMWPE powder, then heating, molding, melting, and solidifying the mixture through hot pressing.

During friction, the nanosheets can form a manganese phosphate film on the material’s surface. This film helps reduce deformation and tearing, improving the composite’s anti-friction and anti-wear properties. The patent reports improvements in friction coefficient, wear depth, and wear width under dry-friction conditions.
