Abstract
The disclosure relates to a reversible adhesive composition including a copolymer between a vinyl spacer monomer unit and a vinyl reversible binder monomer unit. Each monomer unit can be based on acrylate monomer, a vinyl ester monomer, or a vinyl ether monomer, with the spacer monomer unit generally having a shorter pendant chain (such as 1-3 carbon atoms) and the reversible binder monomer unit having a longer pendant chain (such as 3-20 carbon atoms). A corresponding article includes first and second surfaces (or substrates) that are in contact with and bonded to the reversible adhesive composition at an interface therebetween. The reversible adhesive composition generally involves non-covalent and/or non-ionic bonding forces, for example H-bonding, permanent dipole, electron donor-acceptor moieties, and/or van der Waals forces, between the copolymer chains. The first and second surfaces can be repeatedly bonded, separated, and re-bonded while retaining the adhesive strength of the reversible adhesive composition.
