    Abstract: 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.

    Abstract: 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.

    Abstract: A structured organic film (SOF) composite is disclosed, including a structured organic film (SOF), which may include a plurality of segments; a plurality of linkers, where at least one of the plurality of linkers connects at least one of the plurality of segments. The composite also includes a polymer additive incorporated into the SOF. The polymer additive is present in the SOF in a plurality of nanodomains, ranging in size from about 50 nm to about 1 micron. The polymer additive may include a polysulfone. The polysulfone can be poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene). The polymer additive is present in an amount of from about 5 wt % to about 25 wt % based on a total weight of the SOF composite. The structured organic film (SOF) composite may include an ionic segment or ionic capping segment.
