摘　　要：为制备颜色饱和度高、力学性能优良的结构生色海藻酸钙纤维,首先以溶剂热法制备了磁性微球,然后将其分散至聚乙二醇二丙烯酸酯中,使磁性微球在磁场下自组装,在海藻酸钙纤维表面构筑结构色涂层,分析了影响结构生色海藻酸钙纤维显色性能和力学性能的因素。结果表明:当磁性微球的粒径分别为125、145、190 nm时,其在海藻酸钙纤维表面固化后得到了蓝色、绿色和红色的结构色,磁性微球结构色涂层可对海藻酸钙纤维进行较好地包覆,其主要成分为立方相Fe_(3)O_(4),可使纤维的断裂强力由纯海藻酸钙纤维的78 cN分别增加到158、162、169 cN,断裂伸长率也得到了显著提高。To prepare structural colored calcium alginate fibers with high color saturation and satisfactory mechanical properties, magnetic particles were prepared by solvothermal method before dispersing them in the polyethylene glycol diacrylate. A structural color coating was constructed on the surface of calcium alginate fibers by self-assembly of magnetic particles, and factors affecting the color rendering and mechanical properties of the fiber were analyzed. The results show that when the diameters of the magnetic particle are 125, 145 and 190 nm, blue, green and red structural colors were obtained after curing on the surface of calcium alginate fibers, respectively. The coatings of magnetic particles structure color can better achieved on calcium alginate fiber, and the main component is cubic Fe_(3)O_(4). The mechanical properties of the structural colored calcium alginate fibers have been significantly improved, and the breaking strength has been increased from 78 cN to 158, 162 and 169 cN, respectively, along with the improved elongation at break.
