NANOCOMPOSITE HYDROGELS ARE ENGINEERED TO PRESENT SUPERIOR PHYSICAL, CHEMICAL, ELECTRICAL, AND BIOLOGICAL PROPERTIES, OPENING POSSIBILITIES IN DEVELOPING ADVANCED BIOMATERIALS FOR APPLICATIONS THAT WOULD NOT BE POSSIBLE WITH CONVENTIONAL HYDROGELS. CELLULOSE NANOCRYSTALS (CNC) AND LAPONITE ARE NANOPARTICLES WITH ATTRACTIVE MECHANICAL AND RHEOLOGICAL CHARACTERISTICS WIDELY USED IN THE MECHANICAL STRENGTHENING OF HYDROGELS. THUS, THE MAIN OBJECTIVE OF THIS WORK IS TO COMBINE THE USE OF CNC AND LAPONITE NANOPARTICLES WITH CARBOXYMETHYLCELLULOSE (CMC). THE COMBINATION OF CNC AND LAPONITE NANOPARTICLES WITH THE CMC POLYMERIC MATRIX CAN RESULT IN NANOCOMPOSITE HYDROGELS WITH PHYSIOCHEMICAL AND ENHANCED RHEOLOGICAL PROPERTIES, WHICH ENABLE THEIR USE FOR THE 3D EXTRUSION-BASED PRINTING PROCESS.
