Abstract Hybrid hydrogels have gained a lot of attention due to their unique properties which can be tailored for a variety of applications. In this paper, hybrid porous polymers based on sponge-like acetals of polyvinyl alcohol (polyvinyl formals) with functionalized pore structure by pH-sensitive or thermosensitive hydrogels have been synthesized. Synergistic improvement of hybrid hydrogel physicochemical properties (mechanical, swelling, and sorption characteristics) compared to the components from which they were constructed is demonstrated, as well as application of these materials for sorption and removal of model dyes (methylene blue and fluorescein) from aqueous solutions. The hybrid materials have the potential to be used as effective sorbents in numerous applications such as industrial wastewater treatment due to their improved mechanical properties, high-water retention, fast sorption, high sorption capacity, and low cost.
