一种静电纺丝法制备PBT/壳聚糖接枝物纳米纤维膜的方法
摘要：
本发明公开一种静电纺丝法制备PBT/壳聚糖接枝物纳米纤维膜的方法，将PBT、壳聚糖接枝物按照重量百分比配方ω(PBT)/ω(壳聚糖接枝物)=100:2-20通过双螺杆熔融共混制备PBT/壳聚糖接枝物共混粒子；将PBT/壳聚糖接枝物粒子，按照ω(PBT/壳聚糖接枝物粒子)：V(溶剂)=1-20：100溶于溶剂中，恒温水浴中充分搅拌溶解，制成均一PBT/壳聚糖接枝物溶液，即得纺丝前驱体溶液；取上述纺丝前驱体溶液到注射器中静电纺丝，经一定的时间制得纳米纤维膜。这种方法制备的纳米纤维膜组分间具有较好的相容剂性，有较好的机械性能、吸附性能和抗菌功能，可广泛用于高效过滤材料和抗菌医用材料等领域。
摘要（英）：

The invention discloses a method for preparing a PBT/chitosan graft nanofiber membrane through an electrostatic spinning method. PBT and chitosan graft are blended through twin-screw melting according to the weight percentage of 100:(2-20) to prepare PBT/chitosan graft hybrid filler; the PBT/chitosan graft hybrid filler is dissolved in a solvent V according to the weight percentage of (1-20):100, the mixture is fully mixed and dissolved in constant-temperature water bath to prepare a uniform PBT/chitosan graft solution, and a spinning precursor solution is obtained; the spinning precursor solution is put into a syringe for electrostatic spinning, and the nanofiber membrane is prepared after a certain period of time. The nanofiber membrane prepared through the method is good in component compatibility and good in mechanical property, adsorption performance and antibacterial function, and can be widely used in the fields of efficient filter materials and antibacterial medical materials.
