Development of Multifunctional Smart Polymeric Material for Emerging Applications

Le résumé fourni par la source

Abstract Stimuli‐responsive polymers are of great interest due to their multifunctionality and potential across diverse fields. Herein, the synthesis of a dual stimuli‐responsive random copolymer, poly(N‐isopropylacrylamide‐ random ‐L‐lysine methacrylamide) [poly(NIPAM‐ r ‐LysMAM)], prepared via free radical polymerization in water is reported. The incorporation of L‐lysine methacrylamide introduces pendant ─COOH and ─NH 2 groups, enabling pH‐responsive behavior, while the PNIPAM backbone imparts thermo‐responsiveness. The copolymer demonstrates multifunctionality through three distinct applications: i) efficient dye adsorption, achieving up to 97% removal of a model anionic dye (Eosin B) within 24 h, ii) smart window functionality, with reversible and durable thermo‐induced transparency modulation over multiple heating‐cooling cycles, and iii) hydrogel‐based energy generation, where Cu 2+ ‐ and Zn 2+ ‐cross‐linked metallogels serve as electrolytes in galvanic cells, supported by open‐circuit voltage, charge–discharge, and impedance spectroscopy analyses. These results highlight poly(NIPAM‐ r ‐LysMAM) as a versatile multifunctional platform, offering integrated solutions for environmental remediation, energy‐efficient smart windows, and hydrogel‐based electrochemical devices.
