一种海藻酸基/聚吡咯复合纤维的制备

Preparation of Composite Fibers of Alginate Based Polypyrrole

海藻酸钠是来源丰富的天然高分子。分别以氯化钙、盐酸和氯化锰为凝固液，采用湿法纺丝制备了海藻酸钙、海藻酸和海藻酸锰纤维，纤维表面有凹槽结构，其直径为22～45μm。采用高锰酸钾做氧化剂，使吡咯单体在海藻酸基纤维表面聚合，制备海藻酸基/聚吡咯复合纤维，纤维的直径为50～56μm，纤维表面有层状和颗粒状的聚吡咯，复合纤维的比电容值为1.0×10-2～3.0×10-2F/g。

Sodium alginate is a kind of naturally polymer with a lot of source. Alginate based fibers were prepared with wet spin method,with calcium chloride,hydrochloric acid and manganese chloride as solidification liquid solution,the fiber products including the calcium alginate,alginic acid,manganese alginate fibers. The diameter of alginate based fibers was 22-45 μm with groove structure. The alginate/polypyrrole composite fibers had been prepared with pyrrole monomer polymerization on the surface of alginate based fibers in the KMnO4 solution. The alginate/polypyrrole composite fibers with 50-56 μm diameters had layer and granular polypyrrole. The specific capacitances of alginate/polypyrrole film were from 1. 0×10-2 to 3. 0×10-2 F/g. Such fibers owning biodegradability and plenty sources might provide possibitity of the energy storage device in the field of the one-off electronic products.
