Polyvinyl alcohol/Chondroitin sulfate fiber scaffolds were prepared by electrospinning with polyvinyl alcohol and chondroitin sulfate as raw materials

and the optimum preparation scheme of composite porous scaffolds was obtained by orthogonal experiment. The morphology and structure of the fiber scaffolds were characterized by SEM and FTIR

and tested the cytotoxicity and degradation proformance of the material. The results shows that when the volume ratio of polyvinyl alcohol to CS solution is 3 : 1

the spinning voltage is 16 kV

and the injection rate is 0.2mm/min

the spinning effect is the best. The cytotoxicity of the material is 0 or 1

that's to say

the material is no cytotoxicity

the degradation rate is about 75% at 60 days of degradation

so the fiber scaffolds has a good application prospect in cartilage repair.
