ABSTRACT This work describes the preparation of physically crosslinked high molecular weight poly (itaconic acid) (PIA)/Laponite hydrogels. In addition, these bio‐based hydrogels were ionically co‐crosslinked using calcium chloride solution for different times. The interactions cations with carboxylate groups PIA visually checked murexide indicator and confirmed potentiometric titration determining binding capacity, rheology showing an increase in storage loss moduli approach enables us to prepare core‐shell materials a soft hydrogel core shell. release kinetics erythrosine as model compound anionic dye evaluated common mathematical models. ionic co‐crosslinking inhibited diffusion prolonged its release, application potential prepared agrochemical delivery systems.
