Abstract
A simple and effective separation methodology for separating optically transparent adhesive films without damaging the substrate is presented here. Evaporable core–shell nanocapsules embedded with benzenesulfonyl hydrazide were introduced into acrylic films, and could generate nitrogen gas by thermal treatment, inducing the facile separation of the adhesive thin films from the substrate. The heat-triggered gas generation of surface-confined vaporizable nanocapsules created the interfacial openings between the thin film and substrate, and thus accelerated the selective and clear detachment of thin films. In addition, the nanocapsule-embedded adhesive films exhibited the high optical clarity for display applications.
