Abstract
The synthesis of ionic polymer, its solvent‐induced switching behavior, the fabrication of membranes with the thermal‐induced phase separation method (TIPS), and Li^+^ adsorption isotherm on the membranes are described. The polymer membranes prepared with TIPS method show various textures with polymer concentrations. The adsorption isotherm curves of Li^+^ on PEVSA samples show that good adsorption capacity is shown at high pH values, according to the S‐shape of the adsorption isotherm. The ionic polymer film displays the different wettability and morphology after treatments in DI water, dichloromethane, and toluene, and its solvent‐induced surface properties are reversible corresponding to solvents. magnified image
