초록

Herein, double-network (DN) hydrogel beads of calcium alginate/polyacrylamide (PAAm) were synthesized, and their dye adsorption and mechanical performances were enhanced by incorporating cellulose nanocrystal (CNC). The DN hydrogel beads were prepared via two-step procedures: free-radical polymerization of AAm in oil bath at 90 ℃ and ionotropic crosslinking of alginate in calcium chloride solution. The nanocomposite DN beads were fabricated at the CNC contents of 0.5-2 wt% with respect to the polymer amount. Whereas CNC had insignificant effect on the bead structure, it significantly improved both mechanical properties and dye adsorption capacity. Neat and nanocomposite beads exhibited the diameter, weight, and water content of approximately 3.3 mm, 0.04 g, and 88%, respectively, irrespective of the CNC amount. In the dye adsorption, whereas neat hydrogel beads exhibited 19.7% dye removal for the immersion time of 180 min, nanocomposite beads with 1.5 wt% CNC exhibited a 1.8-fold increased dye removal efficiency (35.3%). In addition, nanocomposite beads with 1.0 wt% CNC exhibited 1.8- and 3.8-fold increased compressive modulus and strength (9.0 and 3.0 MPa) compared with those of neat beads (4.9 and 0.8 MPa). Consequently, the DN hydrogel beads with the highest performances were obtained at the CNC content of 1.0-1.5 wt%.
