Effect of Cellulose Characteristics on the Properties of the Wet-Spun Aerogel Fibers

Cellulose aerogels (CAs) from plant or bacterial-derived cellulose have advantages such as low density, high porosity, and specific surface area been used in various applications including biomedical fields. One limiting factor developing CAs is their demanding shaping process since it involves several steps of dissolution/dispersion cellulose, geometry configurations using molds nozzles, coagulation washing the gel body, drying techniques. CA fibers can be converted into textiles enhance design ability, stiffness, flexibility CAs. This study aims to understand correlations between initial characteristics, aerogel’s internal structure, its prospective application. Wet-spun were obtained by supercritical CO2 molecular weight microcrystalline calcium thiocyanate tetrahydrate solution. Fiber spinning, thermal behavior, textural properties, biological assessments inspected. The microfibers proved a higher (~197 m2/g), denser finer nanofibrils (~2 nm) with better stability comparison produced cellulose. nontoxic, cell proliferation was observed over time. showed promising results for tissue engineering wound care.
