PAN基碳纤维的微观结构对电阻率影响的研究

THE STUDIED OF THE EFFECT OF MICROSTRUCTURE ON RESISTIVITY ON PAN-BASED CARBON FIBERS

本文对不同碳化温度下制备的ＰＡＮ基碳纤维的电阻率、结构参数、微晶择优取向度Ｚ°及层面内Ｃ－Ｃ原子键距ａ０进行了测量，给出了ＰＡＮ基碳纤维的电阻率随结构参数（Ｌａ、Ｌｃ、Ｌ００２）的变化规律，同时对碳纤维的电子特性进行了初步讨论．

resistivity,structural parameters,preferred orientation(Z°) and C-C bond Length are measured on PAN_based carbon fibers prepared at different carbonization temperatures,chenge relation of resistivity of PAN_based carbon fibers with structural parameters (L a、L c、d 002 )is given,and electronic properties is discussed preliminarily in the present work.
