Dynamically crosslinked tough adhesive with recyclability

Abstract

A crosslinked adhesive composition comprising: (i) a polymer; (ii) solid particles embedded within the polymer; and (iii) a multiplicity of boronate linkages crosslinking between the polymer and solid particles, wherein the boronate linkages have the formula wherein the polymer and particles are connected to each other through the boronate linkages, and the crosslinked adhesive composition has an ability to bond surfaces and a further ability to thermally debond and rebond the surfaces. Also described herein is a method of bonding first and second surfaces together, the method comprising placing the above-described crosslinked adhesive composition onto the first surface and pressing the second surface onto the crosslinked adhesive composition on the first surface.
