Abstract

A simple model describing the hydrophilic adhesion between solid surfaces, with low roughness is proposed to explain both the influence of the interface roughness and quantity of water present at the interface on the work of adhesion and work of separation. The observed hysteresis between adhesion and separation is explained by the evolving distribution of water along the bonding interface. This model is based on earlier molecular dynamics simulations of hydrophilic direct bonding previously obtained by Cole et al. An experimental validation is presented showing good agreement with model predictions.
