example 1

[0025]Weigh 8g of sodium lauryl sulfate and pour it into a beaker with 95mL of deionized water, place it in an ultrasonic disperser and vibrate ultrasonically for 16min to obtain a self-made dispersion; weigh 24g of carbon nanotubes and pour them into a ball mill. Under the condition of 80r / min, the carbon nanotube powder was obtained by ball milling for 45min. The carbon nanotube powder, the silver nitrate solution with a mass fraction of 32% and the self-made dispersion were mixed in a beaker and stirred at a mass ratio of 1:5:2. 20min, to obtain the stirring solution, the pH of the stirring solution was adjusted to 4 with a mass fraction of 24% nitric acid solution, then the stirring solution was put into a dark greenhouse and mixed and stirred for 1h, vacuum filtration, the filtrate was removed, and the filter residue was taken out. The filter residue was put into an oven and dried for 30 minutes at a temperature of 90°C to obtain self-made silver-loaded carbon nanotubes; w...

Abstract

The invention relates to the technical field of preparation of conductive paper materials, in particular to a preparation method of highly-conductive and antibacterial waterproof conductive paper. Thehighly-conductive and antibacterial waterproof conductive paper is prepared from birch wood pulp fiber as a substrate, self-made silver-supported carbon nanotubes, a carbon fiber dispersion liquid and self-made cationic starch powder as reinforcing agents, as well as polyvinyl alcohol, tributyl phosphate and the like as auxiliary materials. Firstly, modified short carbon fibers are uniformly dispersed in water for obtaining the carbon fiber dispersion liquid, and then the carbon nanotubes are modified with a silver nitrate solution, so that the antibacterial property of the conductive paper is improved; the carbon nano tubes are attached to the carbon fibers and the substrate, a complete conductive network structure is formed, and conductivity of the conductive paper is improved; sweet potato starch is doubly modified with epoxy chloropropane and succinic anhydride, absorption of water can be limited by crosslinking treatment, the waterproof property of the conductive paper is improved, and wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of conductive paper materials, in particular to a preparation method of highly conductive antibacterial and waterproof conductive paper. Background technique [0002] Conductive paper is a functional paper with conductive properties, which can eliminate static electricity through electron conduction and corona discharge. When the conductive layer reaches a certain thickness or the conductive component reaches a certain proportion, it can be used as an electromagnetic shielding material. Conductive paper has the functions of electric conduction, heat conduction, electromagnetic shielding, absorbing electromagnetic waves, etc. It can be widely used in anti-static packaging of various instruments, electromagnetic radiation shielding covers in aviation, aerospace, and precision electronics industries, as well as actuators, sensors, and heat-resistant heaters. wait. [0003] There are two main met...
