Abstract

This application discloses a separator and a preparation method therefor, a battery, and an electric apparatus. The separator includes a substrate and a pressure-sensitive coating, where the pressure-sensitive coating is formed on at least a portion of surface of the substrate. The pressure-sensitive coating includes composite particles and a first plasticizer. The composite particles form bulges on surface of the coating, and the composite particles include polyacrylate particles and inorganic particles. The inorganic particle is present between at least two of the polyacrylate particles, and solubility parameter of the first plasticizer and solubility parameter of the composite particles have a difference with an absolute value of 0.3 MPa-4 MPa.
