PREPARATION METHOD OF C-TYPE CARBON NANOFIBERS BY ELECTROSPINNING

摘要

A method for manufacturing a C-type carbon nanofiber is provided to regulate the cross-section of the carbon nanofiber, by electrospinning polyacrylonitrile as a carbon fiber precursor and thermoplastic polymer using a Y-shaped nozzle and removing the thermoplastic polymer through a thermal treatment process. A PAN(polyacrylonitrile) spinning solution and a PMMA(polymethylmethacrylate) spinning solution are respectively prepared. The spinning solutions are electro-spun through a Y-shaped nozzle(2) to produce a nanofiber. The nanofiber is thermally treated at 300-350°C under an air ambience to obtain an insolubilized fiber. The insolubilized fiber is incinerated under a vacuum condition or an inert ambience to produce a carbon nanofiber having a C-type cross-section.
