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.
