A method for increasing the impact resistance of plastic articles comprising providing a blend of cottonseed oil and plastic resin; fabricating a plastic article from the blend by rotatably screw working the blend into a molten state and molding the molten blend material into the article shape.

A method for continuously preparing graphene powder directly dispersed in an organic system, including: mixing an aqueous graphene oxide dispersion, an emulsifier and an oil-soluble monomer followed by pH adjustment and dispersing to obtain a pre-emulsified dispersion; subjecting the pre-emulsified dispersion to an emulsion polymerization reaction in the presence of an initiator; introducing a reducing agent to reduce graphene oxide; and subjecting the reaction mixture after emulsion polymerization to spray drying to obtain the graphene powder. Equipment used in the preparation method is also provided herein.

The present invention relates, in one aspect, to wax-like and lanolin-like formulations derived from natural-origin materials, particularly gum rosin combined with long-chain alcohols/polyols (fatty alcohols), the esters resulting from the esterification of these substances, and the polyols resulting from the hydroxylation of these esters, as well as its methods of preparation. The formulations of this invention maybe used as synthetic/natural wax substitutes in formulations for products, including but not limited to, cosmetics, foods and beverages, lanolin substitutes, adhesives, packaging and pharmaceuticals.

High spherical particles for use in piezoelectric applications may be produced mixing a mixture comprising a graphene oxide-polyvinylidene fluoride (GO-PVDF) composite, a carrier fluid that is immiscible with the PVDF, and optionally an emulsion stabilizer at a temperature equal to or greater than a melting point or softening temperature of the PVDF to disperse the GO-PVDF composite in the carrier fluid, wherein the GO-PVDF composite has a transmission FTIR minimum transmittance ratio of β-phase PVDF to α-phase PVDF of about 1 or less; cooling the mixture to below the melting point or softening temperature of the PVDF to form GO-PVDF particles; and separating the GO-PVDF particles from the carrier fluid, wherein the GO-PVDF particles comprise the graphene oxide dispersed in the PVDF, and wherein the GO-PVDF particles have a transmission FTIR minimum transmittance ratio of β-phase PVDF to α-phase PVDF of about 1 or less.

Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.
