Substrate with β-type polyvinylidene fluoride film and manufacturing method thereof, and piezoelectric sensor having β-polyvinylidene fluoride film and manufacturing method thereof

摘要

PROBLEM TO BE SOLVED: To provide a substrate with a β type polyvinylidene fluoride film excellent in adhesiveness with a substrate and a manufacturing method therefor, and a piezoelectric sensor equipped with the β type polyvinylidene fluoride film and a manufacturing method therefor.SOLUTION: A substrate with PVDF film 1 contains a substrate 10 containing a resin film 11 and a porous film 12 formed on the resin film 11 and containing at least metal oxide particles or metal hydroxide particles and a PVDF film 20 formed on the porous film 12.SELECTED DRAWING: Figure 1
