NOVELTY - Preparing graphene carbon nanotube flexible conductive film involves grinding the carbon nanotubes by a horizontal mill, dispersing the carbon nanotube powder in an aqueous solution with a surfactant concentration of 0.5-1.5 wt.% to obtain a carbon nanotube dispersion, dispersing the graphene powder uniformly in an aqueous solution with a surfactant concentration of 0.5-2.5 wt. by a cell disruptor to obtain a graphene dispersion, mixing the carbon nanotube dispersion liquid and the graphene dispersion liquid to obtain a graphene carbon nanotube dispersion liquid, adding an appropriate amount of hydroxymethyl cellulose binder and anionic polymer resin emulsion to the graphene-carbon nanotube dispersion, mixing thoroughly and stirring for 0.5-1 hours to obtain graphene carbon nanotube mixture. USE - Method for preparing graphene carbon nanotube flexible conductive film. ADVANTAGE - The method has comfortable hand feeling, water washing resistance, kneading performance, low energy consumption, in simple and eco-friendly manner. DETAILED DESCRIPTION - Preparing graphene carbon nanotube flexible conductive film involves grinding the carbon nanotubes by a horizontal mill, dispersing the carbon nanotube powder in an aqueous solution with a surfactant concentration of 0.5-1.5 wt.% to obtain a carbon nanotube dispersion, dispersing the graphene powder uniformly in an aqueous solution with a surfactant concentration of 0.5-2.5 wt. by a cell disruptor to obtain a graphene dispersion, mixing the carbon nanotube dispersion liquid and the graphene dispersion liquid to obtain a graphene carbon nanotube dispersion liquid, adding an appropriate amount of hydroxymethyl cellulose binder and anionic polymer resin emulsion to the graphene-carbon nanotube dispersion, mixing thoroughly and stirring for 0.5-1 hours to obtain graphene carbon nanotube mixture, adding an appropriate amount of organosilane coupling agent to the graphene carbon nanotube mixture, fully stirring, and sealingly placing at room temperature for 4 hours to obtain a suspension, adding an appropriate amount of flocculation solution to the suspension, fully stirring and standing still to obtain graphene carbon nanotube flocculating solution. The graphene carbon nanotube flocculation liquid is vacuum-filtered and molded with a filter screen for 2 minutes to obtain a wet film. The wet cloth is placed in an infrared drying box and kept at 80 degrees C to dried to obtain a conductive film containing a filter material, used a press roll to press the conductive film containing the filter material, and applied a load of 1kg on both sides, and performed hot drawing in an oven at 100 degrees C until the elongation reaches 10-30% when taken out to obtain product.
