Poly(Allyl Amine), Mw 15,000

Poly(allyl amine) (PAA, PAH) is a cationic polymer with a high density of reactive primary amine groups. It has the ability to modify surfaces and provide cationic character that allows the user to selectively attract negatively charged functional groups to the coated surface.

Applications:

Biomedical & Drug Delivery: Utilized in gene delivery systems and as a functional coating for nanoparticles.

Polyelectrolyte Complexation: Used in layer-by-layer (LbL) assembly for coatings and nanocapsules.

Water Treatment: Functions as a flocculant and coagulant for negatively charged contaminants.

Adhesion Promoter: Improves adhesion to negatively charged surfaces, including biomaterials and composites.
