Abstract

The invention relates to a method for preparing a schemochrome carbon fiber based on a P(NIPAAm-co-AAc) nanosphere. The method comprises the following steps of preparing the P(NIPAAm-co-AAc) nanosphere by adopting an emulsion polymerization method and taking N-N-isopropylacrylamide, N, N-methylene bisacrylamide and sodium dodecyl sulfate as starting materials, mixing the P(NIPAAm-co-AAc) nanosphere together with ultrapure water to obtain a dispersion liquid, putting the dispersion liquid into an annular metal container, putting a single carbon fiber into the center of the container, carrying out electrophoretic deposition via an external electric field, then pulling the fiber out of the container at uniform speed, drying at normal temperature so as to prepare the schemochrome fiber assembled by the P(NIPAAm-co-AAc) nanosphere. The schemochrome fiber prepared by the method has a good optical performance; toxic chemical dye is not required; the method is simple and feasible, and is of important reference value to the environment pollution reduction in the dyeing and finishing industry.

Description

technical field [0001] The invention belongs to the field of fiber dyeing, in particular to a method for preparing structurally colored carbon fibers based on P(NIPAAm-co-AAc) nanospheres. Background technique [0002] As we all know, the traditional dyeing process is to use organic or inorganic dyes to chemically or physically combine with fibers, or to generate insoluble colored substances on fibers. There are a lot of heavy metal ions and toxic intermediates in this process. These harmful substances are discharged. into rivers, lakes and seas, causing serious negative impacts on humans and the environment. Structural dyeing can well solve the contradiction between traditional dyeing and environmental pollution. Structural color is a physical process that causes light waves to scatter, diffract or interfere with the surface microstructure of fibers to produce various colors. It is derived from the bionic concept of butterfly wings and opal structure color development in n...
