Electrospun Fibers from Polysaccharides


Although chitin has limited solubility in common solvents, chitin and chitin derivatives have been electrospun into fibers for various applications. To produce electrospun fibers, chitin was first depolymerized using irradiation and then dissolved using 1,1,1,3,3,3-hexafluoro 2-propanol and fibers with average diameters of 110 nm were obtained [04Min]. After electrospinning, the chitin mats were deacetylated using 40 % aqueous NaOH solution at 60–100 °C to achieve about 85 % deacetylation and form chitosan fibers. SEM images and some of the properties of the chitin and chitosan fibers obtained after deacetylation of the spun chitin membranes are shown in Fig. 58.1. Minimal changes were observed in the diameters of the fibers before and after deacetylation.
