摘　　要：从废旧羊毛中提取羊毛角蛋白对于资源再利用具有重要意义。针对羊毛角蛋白分子量低,难以直接纺丝等问题,将羊毛角蛋白与聚乙烯醇共混制备纺丝液,最后通过静电纺丝制备羊毛角蛋白/聚乙烯醇纳米纤维膜。利用旋转流变仪对羊毛角蛋白/聚乙烯醇纺丝液的黏度进行了分析,利用扫描电镜对羊毛角蛋白/聚乙烯醇纳米纤维的微观形貌进行了表征,采用数字源表对其传感性能进行了测试。结果表明:当聚乙烯醇与羊毛角蛋白的质量比为7∶3时,纺丝黏度适中,获得的纳米纤维粗细均匀,直径约240 nm。羊毛角蛋白/聚乙烯醇纳米纤维膜在手指弯曲运动时产生2.1 V输出电压,可感知人体生理信号,有望应用于柔性传感领域。Hydrolysis wool keratin from waste wool is of great significance for reuse of resource.Flexible wool keratin/polyvinyl alcohol nanofiber film was prepared by electrospinning to solve the problem of difficulty to form film caused by low molecular weight of wool keratin.The morphology of wool keratin/polyvinyl alcohol nanofiber was characterized by scanning electron microscope,and the viscosity of wool keratin/polyvinyl alcohol spinning solution was analyzed by rotating rheometer.The source meter was used to characterize the sensing properties of the nanofiber film.The results show that when the mass ratio of polyvinyl alcohol and wool keratin is 7∶3,the spinning viscosity is moderate,and the diameter of nanofiber film is uniform,about 240 nm.The wool keratin/polyvinyl alcohol nanofiber film generates 2.1 V during the finger bending indicating it can monitor human physiological signals.
