Problems solved by technology

Although the pyrrole layer prepared by gas-phase polymerization of polypyrrole is uniform and dense, the experimental operation is cumbersome and the reaction time is long, which is not conducive to large-scale industrial production.
Ordinary liquid-phase chemical polymerization method, first of all, soak the fabric in a certain concentration of dopant solution for 1 to 2 hours, take it out after fully soaking, put it in a certain concentration of oxidant solution for about 2 hours, and take out the fabric Let it dry at room temperature, but the polypyrrole layer of the composite conductive fabric prepared is not uniform and compact, and the abrasion resistance and solvent resistance need to be improved

Description

technical field [0001] The invention relates to a method for preparing composite conductive fabrics by spray polymerization, which belongs to the technical field of textiles. technical background [0002] In the 1970s, American scientist Hideki Shirakawa, American scientists Higel and McDiarmid discovered that polymer polyacetylene (PAC) has a conductive function. Before that, organic polymers were always regarded as insulating materials. For this reason, the three After winning the Nobel Prize, conductive polymers became a hot topic of research. In subsequent studies, it was found that the conductivity of polypyrrole, polyaniline and other conjugated polymers can reach the level of semiconductor or even metal conductor after doping. By controlling the reaction conditions, such as selecting appropriate solvents and oxidants, polypyrrole can be prepared by chemical oxidation. Its conductivity is as high as 220 s / cm, and it has good thermal, chemical oxidation, and light stab...
