Method for preparing carbon nanometer conductive solution and conductive fibers by using ionic liquids

Abstract

The invention provides a method for preparing a carbon nanometer conductive solution by using water as a solvent and ionic liquids as a dispersing agent, and a method for preparing electric heating fibers by using the carbon nanometer conductive solution. By using a water-based carbon nanometer tube or water-based graphene or nanometer superconductive carbon black dispersing solution or combining the three according to different proportions as a conductive adding material, and water-based resin as an adhering agent and one or a combination of more than two of ionic liquids of imidazolium salt, pyridinium salt, quaternary ammonium salt, quaternary phosphonium salt and the like as a dispersing gent, the conductive solution is prepared by virtue of compounding according to different proportions, and conductive fiber wires / yarns are prepared by dying and drying fiber wires / yarns through the conductive solution, and can be applied to the fields of medical apparatuses and instruments, electronic equipment, aerospace materials, far infrared heating blankets / cushions / clothes, industrial drying and the like. According to the method, the problems that the environment is polluted by a conventional organic solvent and a dispersing agent and agglomeration is easy to occur when a carbon nanometer tube, graphene, nanometer superconductive carbon black and resin are compounded are solved; the method belongs to a green, energy-saving and environment-friendly preparation technology of a carbon nanometer conductive material.
