Popis:	The effect of varying potential upon the stability of a bond formed between an adhesive and an electronically conducting substrate has been examined both theoretically and experimentally. It has been found that, in the presence of a liquid which can wet the substrate and the adhesive, the possibility of adhesive/substrate separation exists, even though the bond might be very stable in the absence of such a liquid environment. Both the inter-facial tension between the liquid and the substrate and specific adsorption at the substrate/liquid interface vary with potential, making the stability of the adhesive/substrate bond potential dependent. In the case of the PTFE/graphite bond in the presence of hot concentrated H3PO4, the measured variations in the rate of separation with potential can be rationalized on the basis of the probable changes in the free energy of the process with potential.
