Abstract

The invention relates to a bacteria cellulose fiber-based carbon nanofiber knitted fabric, which is made through the following steps: adopting spinning and knitting technology to prepare a carbon nanofiber knitted fabric with a superfine bacteria cellulose fiber subjected to refining and carding treatment by the needling, and carrying out pyrolysis carbonization and graphitization. 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 knitted fabric 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 knitted fabric, especially a preparation method of bacterial cellulose fiber-based nano-carbon fiber knitted fabric. technical background [0002] At the end of the 19th century, when people were studying the thermal cracking of hydrocarbons and the disproportionation of carbon monoxide, it was found that there were extremely fine fibrous substances on the surface of the catalyst. This kind of fibrous substances were carbon nanofibers (GNFs or CNFs). Carbon nanofibers are nanofibers formed by curling multilayer graphite sheets. They do not have an obvious hollow structure, and their diameters are generally between 10-500 nm. The structure and performance are in the transition state of vapor-grown carbon fibers and carbon nanotubes. It not only has the characteristics of vapor-grown carbon fibers, but also is very similar to carbon nanotubes in terms of structure, performance and applicati...
