Title:
CORE-SHELL TYPE PARTICLE, USE THEREOF AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP2018172595
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide vinylidene fluoride particles creating an adhesion layer in which clogging of holes on a surface of a separator is reduced even if being subjected to a hot press process.SOLUTION: A core-shell type particle in the present invention includes a core part and a shell part surrounding the periphery of the core part. The core part includes a first polymer including 98 mol% or more of the constitutional unit derived from vinylidene fluoride, and the shell part includes a second polymer including the constitutional unit derived from vinylidene fluoride as a main constitutional unit and different from the first polymer. A melting point of the second polymer is lower than that of the first polymer.SELECTED DRAWING: None
