Super absorbent polymer has wide applications in many fields[1],[2]. Here, we provide two high water absorption regenerated cellulose films. The films were prepared via grafting polymerization and in situ polymerization blending of polyacrylamide (PAM), respectively. Compared with the pure regenerated cellulose film (RC0, 88%), the cellulose film grafted with PAM (RC1) has water absorption of 340%, and the PAM/cellulose inter-penetrating- network film (RC2) has 380% water absorption (Figure 1A). Moreover, the tensile strengths of the films reach 127MPa and 141MPa, which are much higher than that of the pure cellulose (61MPa, Figure 1B). The cycle absorption of water was carried out to indicate the potential of the high water absorption regenerated cellulose films.
