Descrizione

Descrizione generale

Poly(diallyldimethylammonium chloride) solution (PDADMAC) is a cationic polyelectrolyte that is widely utilized as a flocculant. It is prepared by the radical polymerization of diallyldimethylammonium chloride (DADMAC) in presence of a catalyst in the form of an organic peroxide.

Applicazioni

PDADMAC can be used as an electrolytic solution in combination with mesoporous silica to form a responsive carrier system for potential usage in drug delivery. It can be also be coated on gold nanorods to enhance the cellular uptake in biomedical systems. It is used in the surface modification of indium tin oxide (ITO) substrate which may be used in chemical sensors or biosensor based applications.
