Title:
SUPER-ELASTIC ADHESIVE, PREPARATION METHOD AND USE
Document Type and Number:
WIPO Patent Application WO/2023/184815
Kind Code:
A1
Abstract:
The present application belongs to the technical field of super-elastic adhesives, and particularly relates to a super-elastic adhesive, a preparation method and the use. The present application provides a super-elastic adhesive, which comprises an elastic body and an adhesive film layer formed on the surface of the elastic body. The elastic body comprises a first polymer, and the adhesive film layer comprises a second polymer, the length of a molecular chain between cross-linking points of the first polymer being greater than the length of a molecular chain between cross-linking points of the second polymer, and the number of the cross-linking points of the first polymer being larger than the number of the cross-linking points of the second polymer. The super-elastic adhesive in the present application is an adhesive tape having low hysteresis and strong bonding strength, helps to stabilize an electric signal of a flexible electronic device, is more suitable for fatigue working conditions than an existing pressure-sensitive adhesive (viscoelastic adhesive) having high hysteresis and large residual strain, and can relieve adverse phenomena of instability such as creases and wrinkles caused by a viscoelastic adhesive in flexible electronic devices and foldable screens.
