▎ 摘　　要

NOVELTY - A composite comprises disentangled ultra-high molecular weight polyethylene (DUHMWPE); functionalized multiwalled carbon nanotubes (f-MWCNTs); and nanofiller selected from graphene oxide (GO), reduced graphene oxide (RGO), and graphite (Gr). USE - A composite for preparing article (claimed). ADVANTAGE - The UHMWPE composites are melt mixed and injection molded into articles having improved mechanical properties. The use nanofillers help reduce specific consumption of the nanofiller and produce higher performance materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of composite which involves sonicating mixture of functionalized f-MWCNTs, and nanofiller selected from in a 1st fluid medium to obtain 1st dispersion, sonicating DUHMWPE in a 2nd fluid medium to obtain 2nd dispersion, mixing 1st dispersion with 2nd dispersion to obtain homogenized dispersion, and drying homogenized dispersion to form cake, and then particulating the cake to obtain composite in powder form; and (2) preparation of article using the composite which involves melt-mixing the composite at 130-220 degrees C, at a screw speed of 50-250 rpm, and for 5-30 minutes to obtain melt mixed composite and extruding melt mixed composite, followed by injection molding the extrudates into the article at 150-240 degrees C and mold temperature of 25-100 degrees C, at a pressure of 6-10 bar to obtain the article, has tensile modulus of 340-430 MPa and tensile strength of 45-51 MPa.
