Needleless Electrospinning of Pure and Blended Chitosan

Chitosan is a biopolymer with bactericidal, fungicidal, hemostatic and other interesting properties. It can be used, e.g., in medical products, as a filter medium, in biotechnological purposes etc. For these possible applications, nanofiber mats with a large inner surface will be most efficient. This is why in a recent project, the electrospinning properties of pure chitosan as well as chitosan blended with poly(ethylene oxide) were investigated. Using a needleless nanospinning process, the technology under examination can be upscaled from lab to industrial scale, enabling direct transfer of the gained experiences to the intended application.
