Stimuli-responsive polymers are materials that change their properties in response to external stimuli, such as temperature, pH, light, or electric fields. These polymers can undergo physical or chemical transformations, allowing them to adapt their shape, size, or solubility. This unique behavior makes them useful in various applications, including drug delivery systems, sensors, and self-healing materials. The ability of stimuli-responsive polymers to react to specific triggers is often due to their molecular structure, which includes segments that can interact with the environment. Researchers are exploring these materials for innovative uses in fields like biomedical engineering, smart textiles, and environmental remediation, highlighting their potential to revolutionize technology and improve everyday products.
