전기방사와 가교결합을 통한 알지네이트 나노섬유 제조 = Preparation of Alginate Nanofiber via Electrospinning and Crosslinking

다국어 초록 (Multilingual Abstract)

In this study, alginate fiber prepared by electrospinning was crosslinked using CaCl2. In order to improve the spinnability, glycerol was added to the aqueous solution of sodium alginate. The solution containing glycerol exhibited the crossover point of G' and G" at low frequencies and decreased the solution viscosity. A solution containing 4 wt% alginate was suitable for electrospinning and maintained the fiber shape. At higher alginate concentrations, the electrospun fiber transformed into a membrane-like structure. The crosslinked web exhibited improved thermal stability and reduced crystallinity.
