摘要：

In this study, a series of PAN nanofibers with MWCNTs contents range from 1.96 wt% to 5.66 wt% were successfully prepared by electrospinning technique, and thermal conductivity and electrical resistivity were investigated. Firstly, the nanofibers were electrospun, and stabilization and carbonization reactions then occurred by a tube furnace at 280 degree and 1000 degree. The structural features of the obtained composite carbon nanofibers were characterized using scanning electron microscopy (SEM), X-ray diffractometer system (XRD), and Raman spectroscopy. The average thermal diffusivity was measured by using a Laser Flash Analyzer (LFA). The electrical resistivity was evaluated via Sheet Resistance Measurement. With the increasing the mass fraction of MWCNTs to 5.66 wt%, thermal conductivity was conspicuously increased by 33% and electrical resistivity was decreased 80 times.
