Abstract
The invention relates to a method for preparing structural color fibers by electrophoretic deposition. The method comprises the steps as follows: taking methyl methacrylate MMA and potassium peroxodisulfate as initial raw materials; preparing polymethyl methacrylate PMMA nanospheres by adopting an emulsion polymerization method; mixing the PMMA nanospheres with de-ionized water to obtain a dispersion solution; placing the dispersion solution into an annular container; placing a fiber or a bundle of fibers in the center of the annular container; carrying out electrophoretic deposition through an additional electric field; pulling out the fibers from the container; and drying to prepare the structural color fibers assembled by the PMMA nanospheres. The structural color fibers prepared with the method are excellent in optical performance, do not require toxic chemical dyes and have an important reference value for reducing the environmental pollution in the dyeing and finishing industry.
Description
Technical field
