To address the challenges of food waste disposal and promote carbon emission reduction, this study synthesizes hydrogels using nano-calcium peroxide (nano-CaO2) as an oxidant to activate components in waste. With acrylamide (AM), cross-linking agent N,N′-methylene bisacrylamide (MBA), initiator sodium persulfate (SPS), were formed via oxidative excitation free-radical polymerization. A one-factor experiment investigated factors affecting hydrogel preparation, while a four-factor, three-level orthogonal test optimized process. The exhibited swelling capacity 703.1% under optimal conditions: 0.60 g SPS, 0.07 MBA, reaction temperature 70 °C, 0.04 nano-CaO2. Characterization by SEM, XRD, TGA showed that was mainly due interlaced reticulated folded structure microcrystalline formation, with polymer chain interactions contributing excellent properties thermal stability.
