詳細

アプリケーション

Branched polyethyleneimine (PEI) is widely used in many applications due to its polycationic character. Unlike its linear equivalent, branched PEI contains primary, secondary, and tertiary amines. Primarily utilized in industrial applications, high molecular weight PEI has been used as a flocculating agent, textile coating, adhesion promoter, enzyme carrier, and as a material for CO₂ capture.

Polyethylenimine, branched (PEI) is a hydrophilic polymer and a gene carrier, which can be conjugated with dextran to enhance the stability of polycationic vectors. It is also used in the preparation of cationic poly(lactic-co-glycolic acid) (PLGA) nanoparticles for potential usage in gene therapy. PEI can also be grafted on polyacrylonitrile (PAN) fiber membrane for the removal of hexavalent chromium (VI) from wastewater.
