摘　　要：通过湿法纺丝技术制备了海藻/磷虾蛋白复合纤维(SA/AKP),并通过FT-IR、SEM、POM对其化学结构和微观形态结构进行表征,测试了复合纤维在成形过程中的溶胀性能和成品纤维的力学性能。结果表明,磷虾蛋白(AKP)能较好地分散在海藻酸钠(SA)基质中,SA/AKP复合纤维的截面呈圆形和椭圆形形貌,纤维的表面存在粗糙的沟槽结构;复合纤维的溶胀性能随着基质中蛋白质含量的增加而增加,当AKP加入量为30%时,溶胀度达356.3%;纤维的最高断裂强度为2.32cN/dtex,最大断裂伸长率为16.14%。The sodium alginate/Antarctic krill protein（SA/AKP）was prepared by wet spinning technique.The chemical structure and micro-structure were characterized by FT-IR,SEM and polarizing optical microscopy（POM）.The mechanical properties and swelling properties of the composite fibers were tested.It was found that AKP could be well dispersed in the matrix of SA,and the cross-sectional of SA/AKP composite fiber was round and oval shape,while the surface existed rough groove structure.The results indicated that the swelling properties of the composite fibers increased with the increasing protein content in the matrix.When the adding amount of AKP was30%,the swelling degree could reach to 356.3%.The maximum breaking strength of the fiber was up to 2.32cN/dtex and the maximum elongation at break was 16.14%.
