Polyethyleneimine

Polyethyleneimine (PEI) is a colorless to pale yellow, viscous liquid or solid (depending on molecular weight and branching), typically odorless and non-volatile, with no well-defined melting or boiling point due to its polymeric nature. It is a water-soluble, cationic polymer classified as a synthetic polyamine. PEI serves primarily as a functional additive and intermediate in chemical synthesis, valued for its high density of primary, secondary, and tertiary amine groups. It is widely used in water treatment (as a coagulant aid and flocculant), paper manufacturing (as a wet-strength agent and retention aid), and in the formulation of adhesives, coatings, and textile auxiliaries. Additionally, it functions as a crosslinker, dispersant, and surface modifier in polymer composites, biomedical devices, and gene delivery systems.

Polyethyleneimine is used as a polyelectrolyte multilayer on charged surfaces to provide a biocompatible coating on surfaces.1Detergents, adhesives, water treatment, printing inks, dyes, cosmetics, and paper industry, adhesion promoter, lamination primer, fixative agent, flocculant, cationic dispersant, stability enhancer, surface activator, chelating agent, scavenger for aldehydes and oxides.
