Polymer nanocomposites present remarkably enhanced mechanical and tribological properties with respect to their matrices even at a low loading of nanofillers. Here, cupric oxide (CuO) nanoparticles (nano-CuO) were in situ filled into ultra-high-molecularweight polyethylene (UHMWPE) to inhibit a possible agglomeration encountered in the preparation by mechanical mixing. The filled CuO nanoparticles were highly dispersed in UHMWPE with a reliable interface combination. The CuO nanoparticles in the matrix play a role for heterogeneous nucleation, resulting in an enhancement in degree of crystallinity of UHMWPE. The elastic modulus and the elongation at break of the nanocomposites also presented an improvement, indicating a good compatibility between the nano-CuO and the matrix. The average sliding friction coefficient of UHMWPE against 45 # steel was reduced by up to 34% after the in situ filling of CuO nanoparticles, and the wear mechanism was found to transform from adhesive to fatigue wear after the introduction of nano-CuO. It is concluded that the in situ filling can improve the dispersion of CuO nanoparticles in UHMWPE, and markedly promote the mechanical properties and tribological performance of UHMWPE.

“…Fiber‐reinforced composites, so‐called advanced composites, are mostly fabricated using synthetic fibers such as graphite and aramids, and thermoplastic resins such as nylons and polyolefins, or thermoset resins such as epoxies, polyurethanes, and unsaturated polyesters, which are derived from petroleum . These petroleum‐based synthetic fibers, resins, and composites have caused serious ecological and environmental problems owing to their nonbiodegradable nature.…”

Ultra-high-molecular-weight polyethylene (UHMWPE) fibers have been modified by plasma treatment to increase adhesion in high-density polyethylene (HDPE) matrices. Results showed that surface roughness predominates for modified UHMWPE fibers, indicating that the plasma treatment favors the interaction with HDPE. Unmodified HDPE composite samples gave a lower interlaminar shear strength than did the samples that were incorporated with UHMWPE. The addition of unmodified UHMWPE fibers to the neat HDPE significantly increases interlaminar shear strengths of composites, up to 20 vol%. The oxygen concentration increased from 16.16 %to 21.99%, and the ratio of oxygen to carbon atoms increased significantly from 0.194 to 0.284 after oxygen plasma treatment for 5 minutes with a power of 300 W.

“…On the one hand, the superior thermal stability of the nanohybrids enabled the less degradation of the nanocomposites during the melt‐processing. On the other hand, the special beaded structure of different dimensional hybrids and the reinforcing effect of the nano‐silica particles could reduce the adhesive wear as well as abrasive wear to a greater extent .…”

Novel cellulose nanocrystal (CNC)‐silica (SiO2) nanohybrids with a better thermal stability were successfully fabricated by sol–gel method. In this unique hybrid architecture, it was found that silica particles were uniformly adsorbed/anchored by the CNC via covalent bonding and hydrogen bonding. Subsequently, the nanocomposites containing nanofillers (CNC‐SiO2 nanohybrids or CNC), ultrahigh molecular weight polyethylene (UHMWPE), polyethylene glycol (PEG), were prepared by the twin screw extrusion and their properties and structure were systematically investigated. With the incorporation of CNC‐SiO2 nanohybrids (or CNC) into the UHMWPE matrix, the tensile strength, flexural strength, flexural modulus, vicat softening temperature, and crystallinity of the ensuing nanocomposites were significantly increased. Meanwhile, the nanofiller could enhance the wear resistance of UHMWPE. Notably, compared to CNC, the unique beaded structure of CNC‐SiO2 nanohybrids could endow the UHMWPE with an overall superior performance. POLYM.
