Physisorped
WebbIn order to explain the observed measurements at physisorped interfaces, a model previously has been put forward. The Integer Charge Transfer (ICT) model explains why and how charge transfer can occur at an interface consisting of π-conjugated molecules/ polymers and a metallic/semi-conducting substrate.

It is not specific to the adsorbent. It is highly specific to the adsorbent. Physisorption usually occurs at low temperatures. Chemisorption usually occurs at high temperatures. Enthalpy of adsorption is smaller for physisorption.
