General description

(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.

Application

(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.
  • As a precursor to fabricate cartilage mimetic polymer scaffolds that can be used in cartilage regeneration and replacement.

Macroporous polyampholyte hydrogels, simultaneously bearing both the anionic and cationic groups, demonstrate immense promise over the one-sign charged polyelectrolytes, owing to a unique phenomenon known as the ˝anti-polyelectrolyte˝ effect. Thus, they are extremely promising materials, since they remain solvated and
