Description
Shi-Qing Wang leads a 2026 study arguing that stickiness depends on interfacial strength rather than adhesion energy alone. Classic peel theory struggles because measured peel strength dwarfs the thermodynamic work of adhesion by orders of magnitude. Ribbon samples stuck to the same base were pulled in tension at varied speeds and temperatures until they detached.
Detachment stress shifted with speed and temperature exactly as peel strength did in matching peel tests. Peel strength tied directly to that stress through a length scale marking how far deformation reaches from the peel front. Since the scale far exceeds molecular size, peel force reflects the pair-specific interface strength. The stress view unifies both tests under one activated process.
