摘　　要：采用 X射线光电子能谱 (XPS)研究了聚糠醇 (PFA)制备玻璃炭 (GC)过程中的元素组成、相对含量以及表面含氧官能团的类型。结果表明 :PFA基 GC的主体元素组成为 C、O(H除外 )。其中 C元素大多以类石墨碳形式存在 ,表面含氧基团以羟基、醚基为主并伴有一定数量的羰基、羧基、酯基等。By means of X ray photoelectron spectroscopy(XPS), the compositions of elements, atomic concentration as well as the types of surface groups on polyfurfuryl alcohol based glassy carbon(GC)were studied. Results show that carbon and oxygen are basic elements in PFA (besides hydrogen). Most of carbon atoms on PFA are in the form of graphite like carbon. Carbon and oxygen atoms are mainly in the form of hydroxyl group and ether group, also exist as carbonyl, carboxyl groups and inner ester group etc.
