Abstract
Provided are semi -interpenetrating optically clear adhesives, methods of use, and methods of manufacture. An example semi-interpenetrating optically clear adhesive comprises a transparent polymer network comprised of at least two or more interpenetrating polymer networks, wherein at least one polymer network is a thermoset material and at least one other polymer network is a thermoplastic material, yielding an optically clear adhesive with a transparency above 80% and an elastic toughness above 1 MJ/m3.
