(3-丙烯酰胺丙基)三甲基氯化铵水溶液，(3-Acrylamidopropyl) trimethylammonium chloride solution [APTAC]；75 wt. % in H2O

(3-Acrylamidopropyl)trimethylammonium chloride(APTAC) is a quaternary ammonium cationic monomer with high water solubility. It undergoes rapid cationic polymerization due to the presence of a permanent positive charge. It is utilized in the field of stimuli-responsive coatings, biosensors, drug delivery systems, medical devices, contact lenses, dental composites, wound healing, ion-exchange membranes for water treatment, and polymer 3Dscaffolds for tissue engineering.

 

(3-Acrylamidopropyl)trimethylammonium chloride solution can be used:

• As a cationic monomer to synthesize polyampholyte hydrogels (PAHs). These hydrogels show pH-responsive and ionic strength-responsive behavior and are suitable for application in smart coatings and biosensors.
• As a monomer to prepare poly(APTAC) ion exchange membranes with high surface porosity, for the removal of Cu(II), Cr(VI), and As(V) ions from water.[1]
• As a precursor to fabricate cartilage mimetic polymer scaffolds that can be used in cartilage regeneration and replacement.[2]
