Chitosan electrospinning
WebJan 11, 2024 · The chitosan dissolution occurs in 1–10% acetic acid below the pH 6, and a viscous dope is formed. It passes through a candle system filtration unit to remove the undesired impurities and a reservoir for degassing under vacuum around 30 mbar for 5 h to confirm the complete removal of the air bubble. WebThe biological activity of chitosan determines its broad application as a biopolymer for non-woven wound dressings fabricated by electrospinning. The electrospinning process is affected by a large number of different factors that complicate its optimization.
