Preparation of high gamma () phase poly(vinylidene fluoride) piezoelectric materials.

摘要

he piezoelectric and pyroelectric activity ofyinylidene fluoride polymers is enhanced by treating the polymers with a glow discharge at a reduced pressure. The treatment is believed to convert a portion of the a phase crystal content of the polymers to the λ phase. Piezoelectric and pyroeletric elements are formed by metallizing a film of the treated polymer and poling the metallized film.
