polyetyleeniimiini
Polyethyleneimine, often abbreviated as PEI, is a synthetic polymer that consists of repeating ethyleneimine monomer units. It is a water-soluble and highly cationic polymer, meaning it carries a significant positive charge. This cationic nature is key to many of its applications. PEI is produced through the ring-opening polymerization of aziridine, a cyclic amine.
The structure of PEI features a branched or linear chain with numerous primary, secondary, and tertiary amine
Due to its positive charge, PEI readily interacts with negatively charged molecules and surfaces. This property
Other applications of PEI include its use as an adhesive, a coating material, and as a chelating
