- Abstract
Inverted nozzle-pressurized gyration was used as a processing methodology for regenerating cellulose extracted from Laminaria hyperborea for the first time. The viscoelasticity of cellulose/1-ethyl-3-methylimidazolium acetate (EMIM OAc) solutions exhibited high concentration dependence, leading to the production of cellulose products with diverse structures. The regenerated cellulose transitioned from thin films to fibers (≈ 5 μm diameter) as the concentration was increased. The impact of collection distance and working pressure on the morphology and yield of fibers was investigated. This work provides a new sustainable route for processing biopolymers, offering significant potential for applications in biomedicine and healthcare.
