Allgemeine Beschreibung
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.

A self-assembled molecular film of a water-soluble cobalt tetrasulfophthalocyanine was deposited on a gold substrate premodified with poly(diallyldimethylammonium chloride). The process of layer-by-layer assembly on the gold substrate was characterized using UV-Vis, Raman spectroscopy, ellipsometry, contact angle measurements, atomic force

The directional cell migration plays a crucial role in a variety of physiological and pathological processes. It can be controlled by the gradient cues immobilized on the substrate. The poly(sodium 4-styrenesulfonate) (PSS)/poly(diallyldimethylammonium) chloride (PDADMAC) multilayers were post-treated in a gradient

Diffraction-limited, high-contrast photopatterning of the photoluminescence of layer-by-layer films comprising CdSe@CdS@ZnS quantum dots and polyviologen is reported. The photoluminescence of the quantum dots is initially quantitatively quenched due to ultrafast photoinduced electron transfer to polyviologen. Photopatterning is achieved by high-power
