Abstract

Carbonization is one of the key processes for the preparation of polyacrylonitrile (PAN)-based carbon fibers. During the carbonization process, the pore structure within the fiber undergoes complex changes that can be monitored using small-angle X-ray scattering (SAXS). This paper introduces the carbonization mechanism of PAN-based fibers and the basic principles and methods of SAXS, reviews the application of SAXS in the study of the carbonization process of PAN pre-oxidized fibers, and looks forward to the prospect of using synchrotron radiation as the X-ray source for SAXS in situ study of the fiber carbonization process.

同步辐射SAXS在聚丙烯腈纤维原位碳化研究中的应用前景

碳化是制备聚丙烯腈（PAN）基碳纤维的关键工艺之一。在炭化过程中，纤维内部的孔隙结构发生了复杂的变化，可以使用小角度x射线散射（SAXS）来监测。本文介绍了PAN基纤维的碳化机理和SAXS的基本原理和方法，综述了SAXS在PAN预氧化纤维碳化过程研究中的应用，展望了利用同步辐射作为x射线源进行SAXS在纤维碳化过程原位研究的前景。

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
