WebFeb 20, 2024 · STIMULI-RESPONSIVE POLYMERS. Numerous polymers have been reported to possess stimuli-responsive behavior as summarized in many reviews. 17-21 pH-, light-, redox- and thermo-responsive polymers are examples of stimuli-responsive polymers that have been combined with MNPs. In general, the stimuli-responsiveness of a polymeric … WebThe term polymer is a composite of the Greek words poly and meros, meaning “many parts.”. Polymers are large molecules made of small, repeating molecular building blocks called monomers. The process by which monomers link together to form a molecule of a relatively high molecular mass is known as polymerization.
