Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.

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 lubricating film which can effectively reduce wear.

Provided herein are methods of making functional surfaces, including liquid repellant surfaces that can exhibit selective wetting properties. Methods of forming a functional surfaces can comprise providing a dispersion of nanoparticles; and applying the dispersion to a polymer surface to form a multiplicity of re-entrant structures embedded within and protruding from the polymer surface. The re-entrant structures are formed from aggregates of the nanoparticles. Also provided are functional surfaces prepared by these methods, as well as articles comprising these functional surfaces.

The present invention is a laminate film comprising a plastic film, and an inorganic layer and an organic layer containing a 1,3,5-triazine derivative laid on at least one surface of the plastic film, wherein the 1,3,5-triazine derivative has a sulfur-containing group as a substituent on at least one of 2, 4 and 6 positions.

The present invention is directed to a thermoplastic packaging film coated with an antimicrobial coating, a method for the preparation of the coated film and packaging articles made with the film.

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.
