Title:
BARIUM TITANATE FIBER, RESIN COMPOSITION CONTAINING SAME, POLYMER COMPOSITE PIEZOELECTRIC BODY, AND METHOD FOR PRODUCING BARIUM TITANATE FIBER
Document Type and Number:
WIPO Patent Application WO/2021/024833
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a barium titanate fiber which is useful as a filler for a polymer composite piezoelectric body; a polymer composite piezoelectric body which has high piezoelectric properties; and a piezoelectric element utilizing the polymer composite piezoelectric body. A barium titanate fiber which is characterized in that the molar ratio of barium atoms to titanium atoms (i.e., a Ba/Ti ratio) falls within the range from 1.01 to 1.04; a polymer composite piezoelectric body which comprises a resin composition comprising the barium titanate fiber and a polymer; and a piezoelectric element comprising an electrically conductive layer arranged on one surface or both surfaces of the polymer composite piezoelectric body.
