Properties of Polyethyleneimine
Polyethyleneimine (PEI) is a synthetic polymer with distinct characteristics. It exists in two main forms: linear and branched. In its physical state, PEI is often a colorless or pale - yellow viscous liquid. It is highly hygroscopic, readily absorbing moisture from the air. PEI shows excellent solubility in water and ethanol, but it is insoluble in benzene Its aqueous solutions are cationic; a 5% aqueous solution usually has a pH value in the range of 8 - 11. In terms of chemical reactivity, PEI has high reactivity due to its abundant amine groups. These amine groups can participate in various chemical reactions

Applications​

Polyethyleneimine finds widespread applications across multiple industries. In the paper industry, it serves as a retention and drainage aid. It can enhance the wet strength of papers, especially in non - sized absorbent papers like filter papers, blotting papers, and toilet papers. Additionally, it can accelerate the filtration of paper pulp and cause the flocculation of fine fibers in white water. In water treatment, PEI functions as a clarifying aid. Its cationic nature allows it to interact with negatively charged particles in water, facilitating their aggregation and removal. In the field of gene delivery, PEI has been explored as a transfection agent. Its high cationic charge density enables it to form positively charged complexes with nucleic acids efficiently. These complexes can then enter cells, delivering genetic material. In air purification, PEI can be used as an adsorbent for acidic gases, ozone, and aldehydes. Its amine groups can react with these substances, removing them from the air stream.
