Abstract

<jats:title>Abstract</jats:title><jats:p>Effective recycling of mixed materials requires the separation of the different components without the need for toxic solvents. One approach involves utilizing a water soluble coating with reversible photocrosslinkers making it robust until end of life where it can then be dissolved in water after decrosslinking. In this report, we report a novel coumarin methacrylate monomer (COUMA) and its nitroxide mediated copolymerization to create poly((methacrylic acid)‐co‐(styrene sulfonate)‐co‐(coumarin methacrylate)) (P(MAA‐co‐NaSS‐co‐COUMA)) for water‐soluble thin films. Under exposure to light, the coumarin functional groups produces reversible [2+2] cycloadditions which crosslink the resulting polymer films making them no longer water soluble. Characterization of reversible crosslinking behaviour was reported through changes in contact angle and in‐situ rheological characterization. The resulting polymers were successfully integrated into in metal‐insulator‐metal (MIM) capacitors, demonstrating the potential use for water soluble reversible photocrosslinkable dielectric materials for organic electronics.</jats:p><jats:p>This article is protected by copyright.
