Abstract: 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.

Key words: sodium alginate, polypyrrole, fiber, specific capacitances, composite materials
