摘要

奈米孔洞材料在各應用領域之重要性與日俱增，而氣體吸脫附分析儀是對於此類材料之孔洞特性鑑定方法中最普遍的技術。配合適當之數據分析，此技術可用來分析各種不同孔徑大小（從0.5奈米至100奈米）之奈米孔洞材料。本文針對氣體吸脫附分析技術之原理與測量方式進行介紹，另外亦闡明幾種常用以計算孔面積、孔徑大小與微孔量等孔洞特性之數據分析方法。

Nanoporous materials have become more important in various application fields. For the pore characterization, gas physical sorption analysis is a popular and powerful tool for materials with pore diameters ranging from 0.5 to 100 nm. In this article, the principle of sorption analysis and the sorption measurement have been shown. In addition, several analytical methods frequently used for the calculation of surface area, pore diameter and microporosity have also been introduced.
