What is Polyethylene Imine?

Polyethylene Imine is a synthetic polymer composed of repeating units of ethylene and imine groups. Its structure features a high density of amino groups, which makes it highly reactive and capable of forming bonds with various substances. PEI is typically produced through the polymerization of aziridine, resulting in a water-soluble compound that can be tailored for specific applications. Its physical form varies from liquids to powders, depending on the molecular weight and intended use.

PEI’s chemical properties include a high cationic charge density, excellent film-forming ability, and biocompatibility in certain formulations. These qualities make it suitable for applications requiring strong adhesion, charge transfer, or surface modification. Its ability to interact with DNA and other biomolecules also opens avenues in biotechnology and gene delivery. As a result, PEI is increasingly integrated into products that demand precise surface engineering or functional coatings.

How It Works

1. Polymerization: Aziridine monomers undergo polymerization, creating long chains rich in amino groups. This process determines the molecular weight and solubility of PEI.

2. Functionalization: The amino groups can be modified or cross-linked to enhance specific properties like stability or reactivity, tailoring PEI for different uses.

3. Application in Surface Coatings: PEI’s positive charge interacts with negatively charged surfaces, enabling adhesion and surface modification.

4. Binding and Complexation: Its high amine density allows PEI to bind with DNA, proteins, or metal ions, facilitating applications in gene therapy or catalysis.

5. Processing & Deployment: PEI is processed into films, powders, or solutions, depending on the application, and applied through coating, spraying, or embedding techniques.
