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

Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
