Revitalizing Inert Materials: Grafting Self‐Oscillating, Stimuli‐Responsive Organometallic Polymers for Pulsating Systems

Abstract A major challenge in materials science is dynamically adjusting material properties using sensors and control systems. This contribution develops a new approach self‐oscillating copolymer to autonomously change surface response environmental changes. redox‐sensitive terpolymer of N ‐isopropylacrylamide (NIPAM), dimethylacrylamide (DMAc), an iron‐based comonomer ([(phen) 2 (phen‐5‐yl‐acrylamide)Fe II ](PF 6 ) synthesized via Reversible Addition‐Fragmentation Chain Transfer (RAFT) polymerization, catalyzing oscillating redox reaction (Belousov‐Zhabotinsky, BZ). The oscillates from soluble insoluble around 35 °C based on the iron's oxidation state. catechol unit incorporated enhance versatility, enabling grafting onto different surfaces. Optimal BZ reagent concentrations are explored for maximum oscillation amplitude frequency. By selecting working temperature between transition points, copolymer's coil globular conformation observed due oscillations. grafted ultrafiltration membrane, where conformational changes cause variations pore size, leading rapid negative flux peaks that disrupt reduce membrane fouling during protein filtration. study highlights polymers' ability impart dynamic inert materials, paving way smart with self‐regulating adapt changing conditions.
