Abstract
Environmentally sensitive polymeric materials, which exhibit responsiveness to specific external stimuli such as temperature, pH, light, and electric fields, have demonstrated promising application prospects in the field of smart materials. This study focuses on the design and preparation of a series of polymeric materials with excellent environmental sensitivity, exploring their potential applications in drug delivery, sensors, and self-healing materials. By incorporating functional monomers and crosslinkers, advanced synthetic methods including free radical polymerization, RAFT polymerization, and click chemistry were employed to successfully fabricate various responsive hydrogels, nanoparticles, and film materials. The experimental results indicate that the prepared materials exhibit significant volume changes, swelling behavior, or optical property alterations under different stimuli, along with good reversibility and stability. Notably, in pH-responsive hydrogels, highly selective responses within specific pH ranges were achieved by adjusting network structural parameters, providing new insights for targeted treatments of acid-base imbalance-related diseases. Additionally, self-healing coatings based on photoresponsive polymers demonstrated rapid and efficient damage repair capabilities, further validating the practical application value of these materials. This research not only expands the design strategies for environmentally sensitive polymeric materials but also lays theoretical and experimental foundations for their applications in biomedicine and functional devices, offering crucial references for the future development of smart materials..Key Words:Environment-Sensitive Polymers;Ph-Responsive Hydrogels;Light-Responsive Polymers;Drug Delivery;Self-Healing Materials
