Document Type and Number:
WIPO Patent Application WO/2020/111106
Kind Code:
A1
Abstract:
The present invention pertains to a piezoelectric material which contains a vinylidene fluoride/trifluoroethylene copolymer and a (meth)acrylic polymer containing a structural unit derived from a (meth)acrylic monomer represented by formula (I) [in the formula, R1 represents a hydrogen atom or a C1-3 alkyl group, wherein at least one hydrogen atom in R1 may be substituted with a halogen atom; and R2 represents a C1-10 linear or branched alkyl group, a C3-12 alicyclic hydrocarbon group including a C3-6 alicyclic structure, a phenyl group, or a phenyl alkylene group including C1-4 alkylene group, wherein at least one carbon atom in the alkyl group, the alicyclic hydrocarbon group, the phenyl group, and the phenyl alkylene group may be substituted with -O-, -N-, or -S-, at least one hydrogen atom in the alkyl group, the alicyclic hydrocarbon group, and the alkylene group may be substituted with a hydroxyl group, a C1-6 alkyl group, and/or a C1-6 alkoxy group, at least one hydrogen atom on phenyl rings in the phenyl group and the phenyl alkylene group may be substituted with a hydroxyl group, a C1-4 alkyl group, a C1-6 alkoxy group, and/or a cyano group, and at least one hydrogen atom in R2 may be substituted with a halogen atom, provided that at least one hydrogen atom in R1 and/or R2 is substituted with a halogen atom].
