Chitosan peo electrospinning
WebApr 1, 2024 · Here, chitosan/PEO nanofibers were fabricated via electrospinning. At first, 7.0 g acetic acid was added to 3.0 g deionized water to form a 70% acetic acid solution. Subsequently, 0.35 g chitosan and 0.004 g PEO were successively added into the above solution, which then underwent magnetic stirring for 6 h. Webtoo volatile. Electrospinning of pure chitosan solution leads to the formation of beads instead of fine nanofibers. Then, taking into account data from literature [10,17,18,35,36,42], it was decided to mix chitosan with PEO, allowing for better electrospinning. In parallel, to test the compatibility of these two polymers, the …
