Abstract

The invention discloses a filament electrode material and a preparation method thereof. The specific preparation method comprises the following steps of (1) mixing and stirring deionized water and a glacial acetic acid solution evenly, adding chitosan powder to a mixed solution, continuing to stir, standing and discharging bubbles in slurry to obtain slurry A; (2) slowly adding sodium alginate powder to an evenly dispersed graphene oxide solution, quickly stirring, standing and discharging the bubbles in the slurry to obtain slurry B; (3) transferring a drop of slurry A for dripping on the surface of a glass plate and transferring a drop of slurry B for dripping next to the slurry A; (4) inserting two tips of precision tweezers into the slurry A and the slurry B separately, and clamping and extracting the slurry A and the slurry B upwards to form a filamentous line; and (5) standing and suspending the filamentous line obtained in the step (4) to obtain the filament electrode material.The prepared material is simple and convenient to prepare and operate, simple in process, high in speed, low in condition requirement and low in cost.

Description

technical field [0001] The invention belongs to the technical field of polymer functionalized material preparation, and in particular relates to a fiber wire electrode material and a preparation method thereof. Background technique [0002] With the increasing energy crisis and environmental pollution, exploring and developing new environmentally friendly and efficient energy sources is an inevitable choice for the sustainable development of human society. Solar energy is inexhaustible, and the development and utilization of solar energy has been greatly improved in recent decades, based on the first generation of solar cells based on silicon crystals and cadmium telluride and copper indium gallium selenide thin films The main second-generation solar cells have good photoelectric conversion efficiency, but the disadvantages of complex process, high cost, and serious environmental pollution restrict the popularization of the two technologies. Dye-Sensitized Solar Cells (DSSC...
