Patent ID: 8641919

Claim:
A method of making a piezoelectric resin blend comprising the steps of (A) dissolving a piezoelectric polymer or copolymer selected from the group consisting of poly(γ-benzyl α,L-glutamates) (PBLG), poly(γ-methyl α,L-glutamates), poly(γ-ethyl α,L-glutamates), vinyl PBLG, polystyrene, polypropylene, low density polypropylene, polyvinylidene fluoride (PVDF), polyvinylidene fluoride-trifluoroethylene [P(VDF-TrFE)], poly(oxymethylene), nylon 6, nylon 66, nylon 610, epoxies, polyurethanes, cellulose, fluorinated ethylene propylene resins, porous polytetrafluoroethylene (PTFE), and mixtures thereof in a matrix polymer monomer solution, wherein the matrix polymer monomer is selected from methylmethacrylate (MMA), ethylene, vinyl chloride, or 1-butene; and (B) polymerizing the matrix polymer monomer, thereby making a piezoelectric resin blend.
