Fabrication of cotton cellulose based multicomponent polymer fibers via electrospinning

By adding polyvinylidene fluoride(PVDF)and polyvinyl alcohol(PVA)into the solution of cotton cellulose, the spinnability of the solution was improved,so that it provided a method to solve the difficulty of cellulose electrospinning. During the process to improve the spinnability of cellulose solution with the utilization of PVDF and PVA,the ultrafine fibers with good morphology and smooth surface were successfully obtained.By use of PVA in the electrospun solution, the hydrophilicity of multicomponent ultrafine fibrous membrane was also obvious improved.The value of contact angle reduced from 139.3°to 93.9°.
