General description

Poly(diallyldimethylammonium chloride) is a water-soluble cationic polymer that can be prepared from diallyl dimethyl ammonium chloride via free radical polymerization.

It is a positively charged polyelectrolyte that finds application in various fields such as paper manufacturing, the mining industry, water treatment, protein immobilization, separation of biomolecules, removal of bacteria, flocculation of silica and latex particles, and nanocapsule shell formation.

Application

  • Influence of ionic strength on poly(diallyldimethylammonium chloride) macromolecule conformations in electrolyte solutions: Studies the effect of ionic strength on the conformation of PDADMAC in electrolyte solutions. (Z Adamczyk et al., 2014).
  • Comparison of permeability of poly(allylamine hydrochloride) and poly(diallyldimethylammonium chloride)/poly(4-styrenesulfonate) multilayer films: Examines permeability differences in multilayer films of PAH and PDADMAC/PSS. (M Elżbieciak-Wodka et al., 2015).
  • Effect of small molecules on the phase behavior and coacervation of aqueous solutions of poly(diallyldimethylammonium chloride) and poly(sodium 4-styrene sulfonate): Investigates the impact of small molecules on the coacervation of PDADMAC and PSS. (S Huang et al., 2018).
  • Dynamic surface elasticity of mixed poly(diallyldimethylammonium chloride)/sodium dodecyl sulfate/NaCl solutions: Analyzes the dynamic dilational surface elasticity of PDADMAC/SDS/NaCl mixtures. (VV Lyadinskaya et al., 2014).

There is great clinical interest in developing novel nanocarriers for hydrophobic cyanine dyes used as photosensitizing agents in photodynamic therapy (PDT). In the present study we have employed nanoemulsion-templated oil-core multilayer nanocapsules as robust nanocarriers for a cyanine-type photosensitizer IR-786.
