摘    要:以小麦蛋白、聚乙烯醇(PVA)为原料,采用静电纺丝法制备小麦蛋白/PVA共混复合纳米纤维,重点研究纺丝液质量分数、电压、接收距离对纤维形态的影响,利用扫描电镜、傅里叶变换红外光谱、X-射线衍射光谱对纤维的形态与结构进行表征。结果表明:在纺丝液质量分数10%、小麦蛋白与PVA质量比8∶2、电压12 kV、接收距离10 cm的条件下,可以制备平均直径为280 nm左右的均一、表面光滑的纳米纤维。小麦蛋白与PVA复合后,分子间以氢键结合。

关 键 词:静电纺丝  聚乙烯醇  纳米纤维  表征

Abstract:Wheat protein/PVA composite nanofiber was prepared via electrospining technique.The effects of total concentration of the solution,voltages,tip to collector distance and structure of the nanofibers were investigated by scanning electron microscopy(SEM),fourier transform infratred(FT-IR) and X-ray diffraction(XRD).The results indicated that the uniform and smooth wheat protein/PVA composite nanofiber with average diameter of 280 nm could be prepared with following optimal process parameters: total concentration of the solution 10 %,weight ratio of wheat protein to PVA 8∶2,applied voltage 12 kV,and the tip-to-collector distance 10 cm.There were hydrogen bonds between wheat protein and PVA in the composite nanofibers.
Keywords:electrospining  PVA  nanofiber  characterization
