Superabsorbent polymer nanocomposites (SAPCs) are very promising and versatile materials for biomedical applications. In this research work, we focused on a novel nanocellulose‐based SAPC, poly(acrylic acid‐ co ‐2‐hyderoxy ethyl methacrylate)‐grafted cellulose nanocrystal (CNC) composite, P(AA‐ co ‐HEMA)‐ g ‐CNC as a potential drug delivery vehicle and a dye adsorbent. Ceftriaxone and crystal violet were selected as a model drug and dye, respectively. P(AA‐ co ‐HEMA)‐ g ‐CNC was synthesized by graft copolymerization reaction and the product was characterized by FTIR spectroscopy. A proposed mechanism for SAPC formation was suggested and the morphology of the sample was studied by SEM spectroscopy. The swelling of SAPCs was examined in buffer solutions with pH ranged 4‐12. The product exhibited a pH‐responsiveness character so that a swelling‐deswelling pulsatile behavior was recorded at pHs 2 and 8. Drug loading efficiency and drug release profiles of the P(AA‐ co ‐HEMA)‐ g ‐CNC as well as the dye adsorption behavior were studied in detail. Maximum drug encapsulation efficiency and dye adsorption capacity were found to be 89% and 231 mg g −1 , respectively. Conclusively, the obtained results indicated that the synthesized SAPCs could be successfully used as promising drug delivery systems and dye adsorbent materials in wastewater treatment. POLYM.
