preparation example Construction

[0030] The preparation method of the present invention can grow W on the surface of all carbon fibers 18 o 49 Nanomaterials, for the convenience of the preparation process, the diameter of the carbon fiber is uniform, the present invention uses carbon cloth as the presentation form of the carbon fiber in the research and development process, the used carbon cloth (Carbon Fiber Cloth), the abbreviation of the carbon fiber cloth, the fabric of the carbon fiber, is made of pre-oxidized Polyacrylonitrile fiber fabric is made by carbonization or carbon fiber weaving, also known as carbon fiber cloth, carbon fiber cloth, carbon cloth, carbon fiber fabric, carbon fiber tape or carbon fiber sheet (prepreg cloth), etc. In principle all carbon cloths can realize the scheme of the present invention, the carbon cloth used in the embodiment of the present invention is directly purchased at Ce Tech Co., Ltd company, and the model is WOS1002, and the single carbon fiber diameter that forms c...

Embodiment 1

[0034] The WOS1002 carbon cloth purchased at Ce Tech Co., Ltd. was punched and cut into a circular substrate with a diameter of 12mm, placed in a concentrated nitric acid solution at 100°C for 1 hour, washed with deionized water for several times, and dried , Put into the reaction kettle of polytetrafluoroethylene lining (the reaction kettle volume is 50ml) for subsequent use. 0.1g (4g / L) of WCl 6 Add to 25ml absolute ethanol, stir well, when WCl 6After completely dissolving, a yellow transparent precursor solution is formed. Move the precursor solution into a reaction kettle containing carbon cloth, place it in an oven, and react at 160°C for 3 hours. After the reaction is completed, take out the carbon cloth and dry it with deionized water After cleaning several times, the carbon arrangement was dried at 60°C to obtain W 18 o 49 Wrapped with carbon cloth composite material.

Abstract

The invention discloses a W18O49 coated carbon fiber composite material and a preparation method thereof. The W18O49 coated carbon fiber composite material takes carbon fibers as a reaction source and the W18O49 coated carbon fiber composite material is produced by adopting a solvothermal method; a monoclinic W18O49 nano-material grows on the carbon fibers through the solvothermal method in a coating manner; in a solvothermal preparation process, any template and any catalyst are not needed; the technology is simple, the yield is high and the cost is low, so that the W18O49 coated carbon fiber composite material is suitable for batch production; the W18O49 nano-material directly grows on carbon cloth and the prepared nano composite material has a uniform shape and coating tightness and can be used as photocatalysis, electrocatalysis, solar cell, flexible sensor, field emission and lithium-ion battery negative electrode materials.
