Abstract The chemical and physical stability of bio‐hydrogels are utmost interest to avoid the premature degradation polymer favor cyclic material operations (i.e., recovery re‐using). In this work, different alginate hydrogels semi‐interpenetrated with poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate conducting (Alg/PEDOT), which acts as a photothermal absorber is examined. More specifically, behavior Alg/PEDOT ionically covalently crosslinked Ca 2+ ions glyoxal, respectively, has been compared when used water purification platforms. homogenous porosity higher cycling capacity glyoxal‐crosslinked gels provide superior performance for water‐steam generation under sunlight irradiation than that stabilized gel. Furthermore, increasing glyoxal cross‐linking reaction time prove have little effect on efficiency freshwater supply from an artificial seawater solution. Covalent cross‐links thermal (PEDOT:PSS) retention in seawater, critical maintaining such number cycles. This research opens new frontiers promote use biopolymer engineering processes desalination, directly addressing United Nations Sustainable Development Goals Clean Water & Life Land.
