The present invention provides a method for preparing an ultra high molecular weight polyethylene (UHMWPE) composite material including the following steps: providing a substrate material having medical grade ultra high molecular weight polyethylene powders, drying the substrate material to obtain fully dried UHMWPE powders, and pressing the fully dried UHMWPE powders to form a UHMWPE board; immersing the UHMWPE board into a graphene oxide solution and performing an ultrasonic induction by an ultrasonic processor such that the graphene oxide solution infiltrates into the UHMWPE substrate to obtain an ultra high molecular weight polyethylene composite material with excellent biocompatibility and tribological properties. The graphene oxide can be adsorbed and evenly spread on the surface of UHMWPE substrate by ultrasonic induction to form a lurbricating film which can effectively reduce wear.

Melt emulsification may be employed to form elastomeric particulates in a narrow size range when nanoparticles are included as an emulsion stabilizer. Such processes may comprise combining a polyurethane polymer and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or a softening temperature of the polyurethane polymer, applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature, cooling the carrier fluid at least until elastomeric particulates in a solidified state form, and separating the elastomeric particulates from the carrier fluid. In the elastomeric particulates, the polyurethane polymer defines a core and an outer surface of the elastomeric particulates and the nanoparticles are associated with the outer surface. The elastomeric particulates may have a D50 of about 1 m to about 1,000 m.

Melt emulsification may be employed to form elastomeric particulates in a narrow size range when nanoparticles and a sulfonate surfactant are included as emulsion stabilizers. Such processes may comprise combining a polyurethane polymer, a sulfonate surfactant, and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or softening temperature of the polyurethane polymer, applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature, cooling the carrier fluid at least until elastomeric particulates in a solidified state form, and separating the elastomeric particulates from the carrier fluid. The polyurethane polymer defines a core and an outer surface of the elastomeric particulates, and the nanoparticles are associated with the outer surface. The elastomeric particulates may have a span of about 0.9 or less.

The present application relates to an elastomeric article, such as a glove, comprising: (i) an elastomeric film comprising one or more film layers, and including an external surface and an internal surface, (ii) an antimicrobial agent that is effective against both beneficial and harmful microorganisms on the external surface of the elastomeric film, and (iii) a skin-protective agent selected from a probiotic, a prebiotic, or a combination thereof on the internal surface of the elastomeric film; wherein the inner surface of the film is free of an antimicrobially-effective amount of an antimicrobial agent that is effective against both beneficial and harmful microorganisms. The elastomeric articles may further comprise a barrier film layer that provides separation between the antimicrobial agent and the skin-protective agent. Also described are methods for the manufacture of such articles.
