Claim 0:
1. A method of making graphene-oxide-polyvinylidene fluoride (GO-PVDF) particles, comprising:
providing a graphene oxide-polyvinylidene fluoride (GO-PVDF) composite comprising graphene oxide dispersed in polyvinylidene fluoride (PVDF), 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;
mixing a mixture comprising a 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;
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.
