摘要
The piezoelectric and pyroelectric activity of vinylidene 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 alpha phase crystal content of the polymers to the gamma phase. Piezoelectric and pyroelectric elements are formed by metallizing a film of the treated polymer and poling the metallized film.
