| titleOfInvention | Preparation method for composite carbon fiber based on graphene/ polyacrylonitrile |
| abstract | The invention discloses a preparation method for composite carbon fiber based on graphene/ polyacrylonitrile. The preparation method comprises the following steps: adding 0.01-10 parts by weight of initiating agent under nitrogen protection into 1 part by weight of graphene or oxidized graphene, 10-1000 parts by weight of solvent and 10-1000 parts by weight of acrylonitrile monomer; heating to 50-95DEG C; reacting for 1-60 hours; precipitating, carrying out centrifugation, washing and drying to obtain the polyacrylonitrile grafted graphene; dispersing the polyacrylonitrile grafted graphene into polar organic solvent to obtain spinning solution sol; continuously extruding the spinning solution from a spinning head capillary at a constant speed to enter solidification solution; collecting the solidified primary fiber; and drying to obtain the graphene fiber primary silk; and carrying out chemical or thermal treatment to obtain the graphene/ polyacrylonitrile composite carbon fiber. The preparation method is simple and convenient, has simple technology, is convenient and quick for post-processing, and can be produced on a large scale. The obtained graphene/ polyacrylonitrile composite carbon fiber embodies excellent intensity, toughness, modulus thermal stability and electrical conductivity and can be applied in various industrial fields to replace the traditional carbon fiber. |
