Basic theories relating wetting phenomenon on non-ideal surface and porous solids are briefly comprised. The text comprehends thermodynamic principles of wetting, description of contact angle on ideal and non-ideal surface and capillary action with a slight remark to liquid wicking into the irregular pore structures. Further themethods used for contact angle measurement on discrete solids are mentioned which is followed by a concise review of models used for the estimation of surface free energy of solids.
