Title:
ADHESIVE FILM AND PREPARATION METHOD THEREFOR, COMPOSITE COMPONENT, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116537
Kind Code:
A1
Abstract:
The present application provides an adhesive film and a preparation method therefor, a composite component, and an electronic device. The adhesive film is prepared from a prepolymer by means of a cross-linking reaction. The prepolymer comprises an alkyl acrylate soft monomer and an acrylate polar monomer, wherein the mass proportion of the alkyl acrylate soft monomer in the prepolymer is ≥60 wt%, and the mass proportion of the acrylate polar monomer in the prepolymer is <30 wt%. The adhesive film provided in the present application has an excellent low modulus at a low temperature and a high creep recovery rate, and can prolong the service life of a foldable electronic device during the process of repeated folding.
