Description générale

Poly(diallyldimethylammonium chloride) (PDDA) is a cationicpolyelectrolyte that easily ionizes when dissolved in water. This polymer iswidely used in the fields of waste-water treatment (as a flocculant) and the functionalizationof nanoparticles.

Application

Poly(diallyldimethylammonium chloride) can be used as a stabilizing agent in the synthesis of nanoparticles such as capped copper hexacyanoferrate (CuHCF) nanoparticles. The addition of PDDA protects the particles from aggregation and allows the synthesis of nanoparticles with controlled size and polydispersity. It can also be used to fabricate chemical and biological sensors. For example, PDDA-modified catalyst platforms can be used in the electrochemical detection of L-cysteine.

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.
