Description

General description

Poly(allylamine hydrochloride) (PAH) is a water-soluble weak-base and a biodegradable polymer.

Application

Poly(allylamine hydrochloride) can be used as a starting material to prepare:

• Chitosan/PAH polymer blend films by solution casting technique. These films can be employed in injectable drug delivery systems and tissue generation.
• Cross-linked amino-modified graphene oxide for the removal of Cr(IV) from aqueous solutions.
• Polyelectrolyte multilayers(PEMs) by the layer-by-layer method. These PEMs can be used to prepare controlled drug delivery systems and coatings with controlled cell adhesion properties.

Used to make redox hydrogel-modified electrodes for measuring enzyme responses.

Features and Benefits

• Excellent environmental stability
• Water-soluble
• Low cost
