Abstract

The invention discloses a method for preparing hollow carbon fibers with controllable dimensions, and relates to the technical field of carbon fiber preparation. First prepare metal oxide nanorods by hydrothermal method, then mix metal oxide nanorods and polymers in an organic solvent, stir evenly; obtain metal oxide (MOX) / polymer (MP) by electrospinning Blended raw silk; then the blended raw silk is pre-oxidized, carbonized and other heat treatment technologies to obtain MOX / CNF composite carbon fibers, and then pickled, filtered, and dried to obtain hollow carbon fibers. The metal oxide hard template prepared by the hydrothermal method has good scale controllability, and can prepare carbon fibers with hollow structures of different scales. The use of technology can effectively regulate the size of fibers, and can achieve the purpose of mass production.

Description

Technical field

[0001] The invention relates to the technical field of carbon fiber preparation. technical background

[0002] Ordinary carbon fiber has attracted wide attention due to its high specific surface area, good thermal stability, corrosion resistance, and excellent electrical and thermal conductivity. Compared with ordinary carbon fiber, hollow carbon fiber has the advantages of ordinary carbon fiber. Due to the hollow structure, an extra inner surface is added, which greatly improves the performance of adsorption, mass transfer, catalysis, etc. It has good application prospects in the fields of hydrogen storage industry, environmental protection and water purification.

[0003] The traditional hollow carbon fiber preparation technology mainly includes molecular self-assembly method and chemical vapor deposition method. The hollow carbon fiber prepared by molecular self-assembly method has a small diameter, generally no more than 10nm; while the technology of preparing...
