Cellulose has gained significant attention for its abundant sources, degradability, and biocompatibility in achieving the sustainable development goals. However, mechanical waterproof qualities of cellulose-based polymers are typically suboptimal, thereby constraining their potential high-value applications. Moreover, problematic recovery cellulose solvents is challenging resources environment. The aluminum chloride/ zinc water (AlCl3/ZnCl2/H2O) system was utilized as dissolving solvent chemical crosslinking catalyst this investigation, enabling production high-performance films through a "one-pot" approach. By opening ring an acidic solution with epichlorohydrin (EPI), 1, 4-butanediol diglycidyl ether (BDDE), or polyethylene glycol (PEGDGE), efficient achieved, reducing number reagents optimizing film performance all aspects. tensile stress reaches 197.37 MPa elongation at break 33.13%. Furthermore, after soaking 180 days, exhibit good stability without any evident swelling behavior. After being buried soil 20 such could be totally degraded. redissolve AlCl3/ZnCl2/H2O weakening properties. This safe cellulosic more environmentally friendly alternative to plastic packaging film.Furthermore, exhibited high recyclability, salt reaching 83% initial fresh five cycles. excellent efficiency cross-linking approach overall greenness process present novel notion further research.
