摘　　要：以磷虾蛋白(AKP)、海藻酸钠(SA)、聚乙烯醇(PVA)为纺丝原料,通过静电纺丝制备AKP/SA/PVA复合纳米纤维,系统研究了纺丝液浓度和纺丝电压对纤维形貌的影响。通过FT-IR分析复合纤维的结构,结果表明SA与AKP间存在化学反应,而与PVA是物理共混,通过红外的二阶导数和拟合分峰研究共混纤维间的氢键作用,结果表明氢键的类型及含量与纤维构成有关。通过DSC和TGA测试纳米纤维的热性能,表明纤维在250℃左右开始熔融并伴随着分解。With antarctic krill protein(AKP),sodium alginate(SA) and polyvinyl alcohol(PVA) for electrospinning materials,the AKP/SA/PVA Composite nanofibers were obtained by electrospinning,the influences of the concentration of the spinning solution and the spinning voltage on fibers,morphology were studied.The structure of the composite fibers was analyzed by FT-IR,and the result shows that there is the presence of a chemical reaction between the SA and the AKP,while is physical blending with PVA.Menwhile the hydrogen-bond interaction in blending fibers was studied by second derivative infrared spctra and peak-differentiating and imitating,and the result shows that the type and content of hydrogen bonding is related to the composition of the fibers.The thermal properties of nanofibers was tested by DSC and TGA,indicating that the fiber began to melt and accompanied by decomposition.
