Cleanly Removable and Degradable Bio-Based Adhesive for Flexible Displays.

ABSTRACT: In advanced applications such as flexible displays, reusing components is essential for achieving sustainability. However, the removal of acrylic pressure-sensitive adhesives (PSAs), which bond these components, remains a major challenge due to residue formation and the non-degradable C─C backbone. Here, the development of new acrylic PSA alternatives for foldable displays is reported by introducing ultraviolet (UV)-triggered debondability, degradability through lipoic acid analogs, and a visible-light-curing process. PSAs composed of 60 mol% lipoic acid ethyl ester (LpEt) and 3 mol% UV-cross-linkable benzophenone-functionalized acrylic monomers exhibit viscoelastic properties comparable to those of conventional acrylic PSAs, while also enable clean removal from substrates after use.
