Surfactant Can Significantly Reduce Surface Energy Of Water

- Feb 06, 2018 -

Surfactants are substances that add a small amount of material to the interfacial state of the solution system. With a fixed hydrophilic hydrophilic group, the surface of the solution can be arranged in a directional arrangement. The molecular structure of surfactants has two affinity: one end is hydrophilic group, the other end is hydrophobic group, and hydrophilic group is often polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine base and its salts, hydroxyl, amide, ether bonds can also be used as polar hydrophilic groups, and hydrophobic groups are often non-polar hydrocarbon chains, such as 8 carbon atoms above the hydrocarbon chain.

Traditionally, surfactants are a class of substances that can significantly reduce the surface tension of a table even at very low concentrations. With the further study of surfactants, it is generally believed that as long as there is a significant change in the surface properties of the table (boundary) or related to the nature of the material, can be classified as surfactant.
