Based on research by Masanori Ochi and colleagues, thermoresponsive‐interpenetrating polymer network (TR‐IPN) hydrogels containing a large number of chelating groups were synthesized; the hydrogel demonstrates reversible swelling/shrinking property when a solution temperature is below and above critical temperature. Because of the conformational change, the gel can adsorb Cu(II) ion at shrinking state and release it partially at swelling state. Different from other thermoresponsive gel, the TR‐IPN hydrogel consists of independent thermoresponsive polymer and Cu(II) adsorbing polymer. Such unique structure successfully resulted in very large Cu(II) recovery capacity through temperature cycling. DOI: 10.1002/app.46701 .
