Title:
METHOD FOR PREPARING SPACE STRUCTURE FIBER, AND FIBER AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/063094
Kind Code:
A1
Abstract:
A method for preparing a space structure fiber, and the fiber and an application thereof. A low-molecular-weight polysaccharide polyelectrolyte is prepared into a spinning solution by using a wet spinning method, an inert conducting material is optionally distributed in the spinning solution, a high-molecular-weight polysaccharide polyelectrolyte is added into a coagulating tank to serve as a coagulating bath, and the spinning solution is injected into the coagulating bath by means of an injector, so as to obtain the fiber. The preparation method is simple in equipment, low in cost, high in spinnability, and suitable for scale production. The prepared space structure fiber, particularly the hollow multilayer fiber has controllability in the number of layers, the number of cavities and the diameter, good tensile strength, and an ultrahigh specific surface area, and is widely applied in the fields of catalysis, adsorption, filtering, tissue engineering and the like. The prepared space structure fiber, particularly the core-shell structural fiber can be used to prepare linear supercapacitors. The outer shell of natural polysaccharide polyelectrolyte can well prevent short-circuit of two electrodes, and the safety of the capacitor is improved.
