23 Jul Chitosan nanofibre and preparation method and application thereof
Abstract
The invention relates to chitosan nanofibre and a preparation method and application thereof. The preparation method comprises the following steps: (1) dissolving chitosan with acid to obtain chitosan solution; (2) performing phase separation to the chitosan solution obtained in the step (1); and (3) lyophilizing the product obtained in the step (2), washing, and then lyophilizing again to obtain the chitosan nanofibre. The chitosan-based nanofibre prepared by the method of the invention is biodegradable, and has an extracellular matrix-type structure and broad application prospects in fields of tissue engineering, clinical wound repair and the like.
