POLYUREA RESIN COMPOSITION, ORGANIC PIEZOELECTRIC MATERIAL, METHOD FOR PRODUCING THE ORGANIC PIEZOELECTRIC MATERIAL, ULTRASONIC TRANSDUCER USING THE ORGANIC PIEZOELECTRIC MATERIAL, AND ULTRASOUND PROBE

摘要

Disclosed are a resin composition and an organic piezoelectric material respectively used for forming an organic piezoelectric film having excellent piezoelectric properties. Also disclosed are a method for producing the organic piezoelectric material, an ultrasonic transducer using an organic piezoelectric film formed by using the resin composition or the organic piezoelectric material, and an ultrasound probe. Specifically disclosed is a polyurea resin composition or organic piezoelectric material which is characterized by containing a resin which is obtained by a polymerization reaction between a polyurea and a macromonomer having at least two bonds selected from a urea bond, a urethane bond, an ester bond, an ether bond and an amide bond.
