| titleOfInvention | Preparation method of graphene coated carbon-doped PI composite conductive nanofiber long yarn |
| abstract | The invention relates to the field of preparation of polyimide nano fibers, and provides a preparation method of graphene coated carbon-doped PI composite conductive nano fiber long yarn, which at least comprises the following steps: (1) preparing a polyamic acid/hydroxyalkyl cellulose blended spinning solution; (2) preparing a fiber felt and/or a non-woven fabric by electrostatic spinning; (3) dipping the dispersion liquid of the graphene, drying and cutting into strips; (4) heating and drafting to prepare nano fiber oriented tows; (5) twisting to prepare the graphene coated carbon doped PI composite conductive nanofiber long yarn; wherein the graphene has a thickness of 1-10 layers; the mass concentration of graphene in the dispersion liquid is 1.0-5.0%. |
