Discontinuous hollow polylactic acid fiber, and preparation method and application thereof

The invention relates to a discontinuous hollow polylactic acid fiber, and a preparation method and an application thereof. The preparation method comprises the following steps: mixing a regenerated cellulose dispersion with a polylactic acid solution, performing ultrasonic treatment under an ice bath condition, and standing the obtained solution to defoam the solution in order to obtain an oil-in-water Pickering emulsion; and electrospinning the oil-in-water Pickering emulsion to obtain the discontinuous hollow polylactic acid fiber. The discontinuous hollow polylactic acid fiber is applied to in drug loading and tissue engineering. The method is simple and quick; and the use amount of toxic chemicals is reduced, and other raw materials used in the invention are polylactic acid and the like, so the prepared fiber material is biologically nontoxic. 本发明涉及种不连续中空聚乳酸纤维及其制备和应用，将再生纤维素分散液、聚乳酸溶液混合，在冰浴条件下，超声处理，静置消泡，得到水包油型皮克林乳液；将上述水包油型皮克林乳液进行静电纺丝，即得。本发明的不连续中空聚乳酸纤维在载药、组织工程中的应用。本发明方法简单快捷；减少了有毒化学品的使用，同时所用的其它原料为聚乳酸等，因此制备所得
