Background
The dispersant is a surfactant which has two opposite properties of lipophilicity and hydrophilcity in a molecule. The amphiphilic agent is capable of uniformly dispersing solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquids, and also preventing settling and agglomeration of the particles to form stable suspensions.
The dispersant is divided into: anionic type, cationic type, nonionic type, amphoteric type, electric neutral type, and high molecular type (including high, medium, and low molecular weight). Polyvinyl alcohol is a commonly used dispersant, and includes a hydroxyl group in its molecule, but it is poor in water resistance when used as a dispersant, and is liable to be unstable after a long period of use.
Therefore, a new solution is needed to solve this problem.
