Manufacturing method for composite fiber and manufacturing method for composite fiber assembly using the same and composite fiber assembly made by the same

摘要

The present invention relates to a method for producing a fiber material, comprising the steps of: surface treating a fiber material to produce carboxylic acid groups on the surface of the fiber material; forming a mixture of polypyrrole (PPy) or polypyrrole and graphene oxide A step of coating the fiber material with a catalytic metal aqueous solution, and a step of irradiating the fiber material with microwaves to grow columnar carbon nanotubes on the surface of the fiber material.Therefore, since the thickness can be made thinner while satisfying the required rigidity, it is possible to improve the feeling of fit by being flexible.
