Abstract
The invention discloses a method for preparing carbon nano tube conductive paper. The method is characterized by comprising the following steps of: thermally treating carbon nano tubes for 5 to 10 minutes in a microwave oven, performing chemical purification and surface modification, then adding the carbon nano tubes into distilled water, ethanol or acetone solvent, and performing dispersion so that the carbon nano tubes are uniformly dispersed in the liquid; stirring and mixing the carbon nano tube solution and paper pulp, and fully uniformly dispersing the carbon nano tubes and the paper pulp by using a high-speed shearing and emulsifying machine; and manufacturing the carbon nano tube conductive paper by adopting a common papermaking method, performing vacuum drying, then compacting the carbon nano tube conductive paper by using a hydraulic press, and thus obtaining the carbon nano tube conductive paper. The carbon nano tube conductive paper can be cut into required shape and size or directly manufactured into carbon nano tube conductive paper products of specific shape and size, and has double-side electric conductivity; and the shape and the thickness of the conductive paper can be randomly adjusted, and the conductive paper can also be manufactured into conductive three-dimensional structural parts.
