Flexible transparent conductive hydrophobic paper and preparation method thereof

Abstract

The invention provides a preparation method of flexible transparent conductive hydrophobic paper, which comprises the following steps: preparation of transparent hydrophobic conductive ink: uniformlymixing hydrophobic ionic liquid and polymerizable monomers at normal temperature, adding a photoinitiator and a crosslinking agent, and stirring a reaction solution for 1 hour to obtain a prepolymer solution, namely the transparent hydrophobic conductive ink; preparation of a transparent paper base material, namely oxidizing cellulose by using 2, 2, 6, 6-tetramethylpiperidine oxide to prepare nanocellulose, and performing vacuum filtration to prepare transparent paper; and preparation of flexible transparent conductive hydrophobic paper: uniformly coating transparent paper with the prepared transparent conductive ink, and curing under ultraviolet light to obtain the flexible transparent conductive hydrophobic paper. According to the flexible transparent conductive hydrophobic paper and the preparation method thereof provided by the invention, the surface of the transparent paper is coated with the transparent hydrophobic conductive ink layer, and then the coating is formed on the surface of the paper after photocuring, so that the paper is endowed with flexible conductive hydrophobic characteristics.

Description

technical field [0001] The invention relates to the field of paper, in particular to flexible transparent conductive hydrophobic paper and a preparation method thereof. Background technique [0002] Because paper is renewable, environmentally friendly, light, mechanically flexible, and disposable, it has some shortcomings: paper has good electrical insulation, and its mechanical strength is average. Because paper contains hydrophilic functional groups, it has very good properties. Hygroscopicity leads to its own swelling, and the surface of the paper is easily stained by the external environment and is not easy to clean; when compounded with other compounds, it will reduce the mechanical properties of the material and even affect the service life of the material. Therefore, it is necessary to make paper widely used in more fields, especially in energy sources such as microelectronics products, batteries, and even solar energy. (1) The paper must have good hydrophobic proper...

[0002] Because paper is renewable, environmentally friendly, light, mechanically flexible, and disposable, it has some shortcomings: paper has good electrical insulation, and its mechanical strength is average. Since paper contains hydrophilic functional groups, it has very good properties. Hygroscopicity, leading to its own swelling, and the surface of the paper is easily stained by the external environment and is not easy to clean; when compounded with other compounds, it will reduce the mechanical properties of the material, and even affect the service life of the material

However, the preparation process of this method is complicated, the process is various, and the cost is high; and the introduction of all-black carbon nanotubes as the conductive component will have the defect of mutual restriction of conductivity and optical transparency.
