Azobenzene‐Containing Triblock Copolymer Adhesive Based on Light‐Induced Solid–Liquid Phase Transition: Application to Bonding for Various Substrates

Front Cover: In the article number 1900105, Haruhisa Akiyama, Hideyuki Kihara, and co-workers demonstrate the repeatable bonding/debonding of various substrates such as plastics and metals by using photoresponsive adhesive tapes consisting of an azobenzene-based triblock copolymer. The adhesive allows phototuning of the adhesion strength, easy detachment of the substrate, and facile removal of the adhesive residue remaining on the substrate without any damage to the substrate.
