Embodiment 1

[0025] Place the bleached bacterial cellulose wet film between a pair of holding rollers with a diameter of 20mm, and feed it at a certain speed (10 mm / min); through a polishing wheel composed of needle-shaped, superhard, and elastic stainless steel wires Needle-like carding on the surface, high-speed puncture, splitting and carding, transforming the bacterial cellulose wet film into bacterial cellulose fibers; filtering the bacterial cellulose superfine fibers through a filter press to prepare bacteria with 100% water content Cellulose microfiber strips. The ultrafine fiber diameter is 100nm, and the ultrafine fiber length is 40mm. The above bacteria cellulose superfine fiber strips are processed by opening, carding, netting, slivering, spinning and other processes to form bacterial cellulose superfine fiber yarns, which are then processed into woven fabrics through a weaving process. After the above bacteria cellulose microfiber woven fabric is treated with liquid nitrogen,...

Abstract

The invention relates to a preparation method of bacteria cellulose fiber-based carbon nanofiber woven cloth, which is characterized in that the bacteria cellulose fiber matrix carbon nanofiber woven cloth is made through the following steps: adopting spinning and machine-made technology to prepare a carbon nanofiber woven cloth with a superfine bacteria cellulose fiber subjected to refining and carding treatment by the needling, and conducting pyrolysis carbonization and graphitization on the carbon nanofiber woven cloth. The preparation method has the benefits that the raw material source is wide; the price is low; the processing method is environment-friendly, safe, simple and efficient; the bacteria cellulose fiber-based carbon nanofiber woven cloth gained after processing has wide application fields; and the potential economic benefit is huge.

Description

technical field [0001] This patent relates to a preparation method of nano-carbon fiber woven cloth, especially a preparation method of bacterial cellulose fiber-based nano-carbon fiber woven cloth. technical background [0002] As a new type of carbon material, carbon nanofiber has excellent physical and mechanical properties and chemical stability, such as low density, high specific modulus, high specific strength, high specific surface area, wave absorption, electrical conductivity, and thermal conductivity comparable to graphite and thermal stability. In recent years, research on carbon nanofibers has aroused widespread interest. A variety of nano-carbon crystals, needles, rods, barrels, etc. emerge in endlessly. Carbon nanotechnology is extremely versatile and has been applied in aviation, aerospace, military, energy, automobile, food, light industry, textile, IT, medicine and other fields. With the continuous deepening of research on carbon nanofibers and the wide a...
