Intermolecular and surface interaction characteristics determine the physiochemical properties and functionalities of materials in different applications. Quantitative characterization of the intermolecular and surface interaction mechanisms of soft materials (e.g., surfactants, polymers, biopolymers) and engineering systems (e.g., stabilization/destabilization of water-in-oil or oil-in-water emulsions, oil/water separation, bubble flotation, removal of pollutants and fine solids from wastewater) has attracted much research interest over the past decades. In this talk, I will discuss the development of research field on intermolecular and surface forces. The basics of intermolecular and surface forces and the commonly used nanomechanical techniques will be also briefly introduced. The recent progress on how we applied these advanced nanomechanical techniques for quantifying intermolecular and surface interactions of different material and engineering systems (e.g., oil production, wastewater treatment), as well as for developing new functional materials, will be presented.
