中间相和各向同性沥青基炭纤维的活化及其结果比较

ACTIVATION OF MESOPHASE AND ISOTROPIC PITCH-BASED CARBON FIBERS AND COMPARISON OF THE RESULTANT FIBERS

研究了分别由中间相沥青和各向同性沥青为原料制备的两种活化纤维的结构与性能特征。通过低温N2气吸附等温线测定、扫描电镜（SEM）观察和X－射线衍射分析等方法，从微观结构上比较了两种沥青作为ACF制备原料的差异性。

The structure and properties of two kinds of pitch-based activated fibers prepared from mesophase pitch and isotropic pitch,respectively,are studied in this paper. By means of N2 adsorption isotherm,scanning electron microscope (SEM) and X-ray diffraction (XRD), the difference between isotropic pitch and mesophase pitch used as the precursors material of ACF are compared from the aspect of microstructure.
