Beschreibung
Zusammenfassung:	The invention relates to the technical field of medical dressings, in particular to a core-shell structure electrospinning nanofiber dressing which is prepared through an electrospinning method and has antibacterial and drug sustained release functions. In order to prepare a wound dressing with antibacterial and drug sustained-release functions by taking polycaprolactone (PCL), chitosan (CS) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) as main raw materials, the invention provides an antibacterial electrospinning nanofiber dressing which comprises the following components in percentage by mass: 13.24-13.25% of polycaprolactone, 0.37-0.74% of chitosan, 0.37-0.37% of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) and the balance of water. And the content of the hydroxypropyl-beta-cyclodextrin is 35.4%-38.3%. The wound dressing prepared by the invention has good mechanical strength, good biocompatibility and good commercial application prospects. 本发明涉及医用敷料技术领域，尤其涉及一种通过静电纺丝法制备的具有抗菌、药物缓释功能的核壳结构电纺纳米纤维敷料。为了以聚己内酯(P
