Embodiment 1

[0084] Example 1 The preparation process of the flexible carbon nanotube / zinc oxide monochromatic ultraviolet fluorescent film comprises the following steps:

[0085] Step 1: Pull out a carbon tube film with a width of about 1.7 cm and a length of about 3 cm from the spinnable array and put it on the copper frame.

[0086] Step 2: Weigh 0.1g of zinc acetylacetonate and lay it on the porcelain boat, so that the width of the laying is basically equivalent to the width of the two carbon tube films. The edge basically coincides with the wide edge of the precursor tile, and the film as a whole is located directly above the precursor, and it is covered with another porcelain boat of the same size, with a gap of about 3mm.

[0087] Step 3 Place the whole object obtained in step 2 in the heating center of the quartz glass tube of the horizontal tube furnace, with both ends of the tube open. Start from room temperature and heat at a rate of 7°C / min. When the temperature rises to 17...

Embodiment 2

[0092] Example 2 This implementation will list as an extension of the preparation process of the flexible carbon nanotube / zinc oxide monochromatic ultraviolet fluorescent film material, and introduce the self-supported graphene oxide-zinc oxide nanoparticle composite film on the fire-resistant mosquito net with grid The preparation process comprises the following steps:

[0093]Step 1: Immerse the fire-resistant and anti-mosquito screen curtain cloth in the pre-prepared aqueous dispersion of graphene oxide with a concentration of 2mg / ml for 1min, then take it out and dry it in an oven at 60°C to form a self-supporting oxidized layer on the grid. Graphene film screen cloth.

[0094] Step 2: Place the screen cloth with graphene oxide film distributed on the grid in step 1 horizontally on the porcelain boat with 0.1g zinc acetylacetonate precursor, so that the grid with self-supporting graphene oxide film distribution Located directly above the precursor, cover it with another...

Abstract

The invention discloses a flexible nanocarbon / zinc oxide monochromatic ultraviolet fluorescence film and its preparation method and application. The monochromatic ultraviolet fluorescence film comprises a carbon nano-material film and ZnO nano-particles deposited on the carbon nano-material film, wherein the carbon nano-material film is mainly composed of graphene oxide with a planar sp2 surface state or a plurality of carbon nanotubes which are parallelly distributed in a set direction and arranged at intervals and have a curvature sp2 surface state. The preparation method comprises the following steps: providing a self-supporting carbon nano-material film, arranging a zinc source right below the carbon nano-material film, heating the zinc source to be evaporated and decomposed and depositing the ZnO nano-particles on the carbon nano-material film. The flexible nanocarbon / zinc oxide monochromatic ultraviolet fluorescence film of the invention has monochromatic ultraviolet excitation light characteristics and can be easily transferred. In addition, the preparation technology is simple and low-cost and can be widely applied in fields of laser technology and the like.

Description

technical field [0001] The invention relates to a nano-carbon material-inorganic semiconductor nano-structure composite film material, in particular to a flexible nano-carbon / zinc oxide monochromatic ultraviolet fluorescent film, its preparation method and application, and belongs to the field of nano-micro composite materials. Background technique [0002] Zinc oxide (ZnO), as a semiconductor material with wide bandgap (3.37eV) at room temperature and exciton binding energy up to 60meV, has become another star material after gallium nitride due to its superior ultraviolet photoluminescence performance at room temperature. In the field of photoelectricity, piezoelectricity, laser, and photocatalysis, it gradually shows its powerful multifunctional characteristics. At present, the preparation methods of nano-ZnO mainly include sol-gel (sol-gel), hydrothermal and solvothermal methods, thermal evaporation, laser ablation evaporation, chemical vapor deposition (CVD), atomic laye...
