Collagen obtained from jellyfish collected from the Sea of Marmara and marine-derived chitosan were chosen as monomers. Superabsorbent polymers were characterized using FT-IR, SEM, and DSC. The swelling capacities of superabsorbent polymers were measured and compared. The maximum water absorption capacities in saline solution were 79 and 136 g/g for chitosan-polyacrylic acid and collagen-polyacrylic acid superabsorbent polymers, respectively. The highest water retention capacities of chitosan-polyacrylic acid and collagen-polyacrylic acid superabsorbent polymers were calculated as approximately 70 times and 120 times their weight, respectively. Fickian diffusion and pseudo-second-order kinetics were applied to determine the swelling kinetics, revealing a perfect relationship. Consequently, the superabsorbent polymer synthesized with collagen obtained from jellyfish had a higher water absorption capacity. To our knowledge, no prior research has documented the production of a biobased superabsorbent derived from jellyfish (Aurelia aurita) in the Sea of Marmara. Hence, this study represents a novel and valuable contribution to the literature. Moreover, the increased use of biodegradable biobased superabsorbent polymers can help reduce the carbon footprint and mitigate environmental pollution.
