With the advantages of carboxyl functional groups as the core structure, it supports the application of intelligent materials and highly absorbent systems:
Hyperabsorbent materials: carboxyl groups provide excellent hydrophilicity and ion exchange ability. The polyacrylic cross-linking network can quickly absorb water and expand to form gels. It is widely used in infant diapers, hemostatic dressings and other fields;
Intelligent responsive materials: PAA can undergo ionization changes under different pH conditions, giving it pH responsiveness, and is often used to build smart gels, drug sustained-release systems, etc.;
Adhesives and coatings: Good adhesion and film forming properties make them widely used in water-based adhesives, architectural coatings and thickening systems, with good transparency, flexibility and environmental protection characteristics.
