일반 설명
Poly(ethyleneimine) (PEI) is a positivelycharged polymeric amine with a linear or branched structure. It has chelating properties with a variety of metal ions. It is highlysoluble in water and behaves as an effective base in aqueous solutions. Due toits superior physicochemical properties, it is widely used in the field ofbiomedicine, water purification, bioimaging, gene delivery, and self-healingmaterials.
애플리케이션
Poly(ethyleneimine) solution can be used for surface modification of cation exchange resins. The modified resins exhibited improved selectivity towards transition elements. Due to repulsion effects within the cationic layer, the selectivity for alkaline ions decreases. As a result, this resin can be applied to purify industrial waste by column sorption.
It can be used as a precursor to prepare polyelectrolyte multilayers for the promotion of cell adhesion and growth on implant surfaces.
PEI can act as a reactive template and stabilizing agent in the preparation of metal nanoparticles in aqueous media. The amino groups in the PEI can coordinate with metal ions dissolved in water and reduce their aggregation capability. This results in the formation of smaller nanoparticles.

특징 및 장점
- It has repetitive structural units and aflexible polymer chain.
- Due to the accessibility of a huge number ofamino groups on PEI, it can be modified or functionalized for specific featuressuch as sensitivity, specificity, and biocompatibility.
- Highwater solubility.
