Preparation of carbon membranes for gas separation

Polymeric membrane materials were recognized as a promising tool for gas separation. However, these polymer membranes are deficient to meet the requirements of membrane technology, especially operation at high temperature and harsh environment. In the recent decades, membrane materials based on carb...
