Preparation and Characterization of Electrospun Polyacrylonitrile-Based Copolymer |
| 초록 |
In this work, carbon nanofibers were produced from a polyacrylonitrile based copolymer and N,N-dimethylformamide precursor solution by an electrospinning process and later carbonizated at temperatures ranging from 300 to 1000 ℃ in an N2 atmosphere for about 20 h. The morphological structure of the nanofibers was studied with scanning electron microscopy. Scanning electron microscopy (SEM) images of carbonized polyacrylonitrile nanofibers showed that the carbonized polyacrylonitrile nanofibers possessed electrical properties. The thermal behavior of the nanofibers was studied with thermogravimetric analysis. An indirect four-point-probe method was used for the measurement of the conductivity of nanofiber webs. |
