Abstract

The invention is a method and device of preparing high-performance continuous cobalt oxide fiber, including: using acetylacetone and cobalt oxide as main raw materials to synthesize a precursor cobalt acetyl-acetonate polymer, dissolving the precursor in methanol to obtain spinning solution, using dry-spinning to obtain continuous precursor fiber, making thermal processing of sintering to obtain continuous cobalt oxide fiber, adopting special atmosphere thermal processing process on the precursor fiber, and blowing air flow to the continuous cobalt oxide fiber at high temperature so as to strengthen the fiber extensibility. The thermal processing is made in a functional sintering furnace which contains inner pipe, outer pipe, and heater wire coiled on the outer pipe, and at the time of aerating, the air flow can be radiantly blown out through a fine slit in the inner pipe. The process of the invention is simple and easy to operate, able to prepare smooth and uniform continuous cobalt oxide fiber with tensile strength over 2.6 Gpa and length able to be several kilometers.
