To develop a systematic understanding of polymer–surfactant … Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. Surfactants may function as emulsifiers, wetting agents, detergents, foaming agents, or dispersants. The word "surfactant" is a blend of surface-active agent, coined c. 1950. Agents that increase surface tension are "surface active" in the literal sense but are not called su…
