摘 要:借助于扫描电镜和光学显微镜,研究了PAN基中空炭纤维的径向结构,实验结果表明,由实验室制备的中空炭纤维主要可分为两类,即圆形和扁形中空炭纤维,且它们具有不同的形成机理。通过炭纤维抛光面的偏光显微镜分析,提出了两种炭纤维的径向结构示意图。The radial textures of PAN based hollow carbon fibers have been studied by means of a scanning electron microscope and an optical microscope.The results showed that the hollow carbon fibers made in our laboratory can mainly be divided into two types: circular and elliptical hollow carbon fibers which have different formation mechanism. The schematic of the radial textures of two hollow carbon fibers was proposed by examining the polished cross-section of carbon fibers under polarized light microscope.
