MODIFIED PHENOLIC-RESIN FIBER AND METHOD FOR FABRICATING SAME AND USE OF SAME, AND COMPOSITE MATERIAL MADE OF SAID MODIFIED PHENOLIC-RESIN FIBER AND USED FOR ELECTRODE

摘要

The present invention relates to a method for fabricating a modified phenolic-resin fiber, comprising: compositing a graphene substance, a co-spun polymer, and phenolic resin to obtain phenolic resin containing graphene; spinning the obtained graphene-containing phenolic resin to obtain a phenolic-resin-fiber raw fiber, then curing and crosslinking to obtain a modified phenolic-resin fiber. Also provided are a composite material used for an electrode, and a method for fabricating same, and said composite material may be made of the described modified phenolic-resin fiber.
