An electrochemically disbondable composition is provided having a matrix
functionality and an electrolyte functionality. The matrix functionality
provides an adhesive bond to a substrate, and the electrolyte
functionality provides sufficient ionic conductivity to the composition
to support a faradaic reaction at an interface with an electrically
conductive surface in contact with the composition, whereby the adhesive
bond is weakened at the interface. The composition may be a
phase-separated composition having first regions of substantially matrix
functionality and second regions of substantially electrolyte
functionality. Adhesive and coating compositions and methods of
disbonding also are described.
