In modern industries, the disassembly of components for the purpose of reuse or recycling plays a crucial role in waste reduction and minimizing production costs. This study presents the fabrication of an optically clear adhesive (OCA) for foldable displays using visible light, as well as the development of a UV-debondable adhesive achieved by reducing adhesion through supplementary UV curing. The utilization of this UV-debondable adhesive enables effective layer delamination through a reduction of adhesion via UV irradiation, facilitating an efficient reusing process. The adhesive was prepared by incorporating a visible light curing system and a benzophenone-based monomer, thereby eliminating the need for heat and solvents while relying solely on light sources of varying wavelengths. Additionally, molecular dynamics simulations were conducted to investigate the alterations in the polymer network, with the aim of comprehending the underlying factors contributing to the decrease in peel strength following additional UV irradiation
