Nanofibers and preparation methods therefor |
| abstract |
The present invention discloses a method for preparing graphene nanofibers and non-woven fabrics using a fluid with a ultra-high draw ratio by means of a high-voltage electrospinning method. Compared with other methods for preparing graphene fibers (such as wet spinning, air-assisted spinning, etc.), the graphene fibers obtained by the present method have smaller diameters (about 100 nm to 500 nm) and a higher yield. The fibers themselves have better mechanical and electrical properties. The invention discloses a method for preparing ultra-fine graphene nanofibers and non-woven fabrics by electrospinning a mixed spinning liquid system of polymer and graphene oxide (the polymer is sodium polyacrylate). This method is highly efficient and environmentally friendly, and the resulted graphene nanofibers are the thinnest graphene fibers as currently known. |
