We report the first observation of an isotope effect in adhesion. A significant increase in adhesion hysteresis was observed when the OH groups at the -Si-OH and -P(O)(OH)2 surfaces were replaced by OD groups. Our observations support the mechanism of H-bonding with PDMS chains, and also confirm that dissipative processes dominate adhesion and adhesion hysteresis behavior.
