| titleOfInvention | Preparation method of wood-based carbon nanotube composite conductive film |
| abstract | The invention provides a preparation method of a wood-based carbon nanotube composite conductive film, which comprises the steps of preparing a wood substrate with a multi-scale pore structure by using wood chips as raw materials, uniformly dispersing carbon nanotubes by using nano cellulose as a dispersing agent to form a mixed solution, carrying out vacuum impregnation on the mixed solution into a wood substrate with the multi-scale pore structure, forming hydrogel on the complex, carrying out freeze drying on the hydrogel to form aerogel, and finally carrying out humidity conditioning treatment and pressing the aerogel to form the wood-based carbon nanotube composite conductive film. The invention adopts the wood-based cellulose as the supporting frame, and has excellent mechanical strength; the carbon nano tubes are uniformly distributed in the wood chips to form a uniform conductive network structure, so that the prepared product has higher conductivity; a large amount of hydrogen bonds can be formed by utilizing the hydroxyl of the nano-cellulose and the hydroxyl on the wood cellulose in the hydrogel forming process and the hot pressing process, so that the interface bonding force between the nano-cellulose and the wood cellulose is improved, and the stability of the integral structure of the composite material is improved. |
