The LPSQ polymer was blended with various diene crosslinkers and its reversible features were evaluated. LPSQ adhesives with long alkyl crosslinkers, including LPSQ-Oct and LPSQ-Dec, exhibit tremendous reversibility in thermally switchable adhesion. The effect of the chain flexibility of LPSQ side chains on the reversible Diels-Alder and retro Diels-Alder reactions was experimentally and theoretically demonstrated. Moreover, these thermally switchable LPSQ adhesives present excellent mechanical and thermal stabilities compared to commercial adhesives, and they are expected to be potential materials for adhesion applications.
