[摘要] 碳膜由于其在腐蚀性和高温操作中具有更高的选择性、渗透性和稳定性而受到关注。碳膜可以通过在控制条件下对合适的聚合物前驱体进行热解来制备。本文对碳膜的制备方面进行了综述，可以分为六个步骤：前驱体的选择、聚合物膜的制备、前驱体的预处理、热解过程、热解后膜的后期处理和模块的构建。通过对预处理变量、热解工艺参数和后处理条件的控制，为提高碳膜的分离性能提供了机会。通过了解现有的方法，人们可以在碳膜的制备过程中选择和优化最佳的技术。此外，还简要指出了碳膜研究在气体分离领域未来的潜在研究领域。

[Title] Fabrication of carbon membranes for gas separation––a review

[Author] S.M. Saufi, A.F. Ismail

[Abstract] Carbon membrane materials are becoming more important in the new era of membrane technology for gas separation due to their higher selectivity, permeability and stability in corrosive and high temperature operations. Carbon membranes can be produced by pyrolysis of a suitable polymeric precursor under controlled conditions. This paper reviews the fabrication aspects of carbon membranes, which can be divided into six steps: precursor selection, polymeric membrane preparation, pretreatment of the precursor, pyrolysis process, post-treatment of pyrolyzed membranes and module construction. The manipulation of the pretreatment variables, pyrolysis process parameters and post-treatment conditions were shown to provide an opportunity to enhance the separation performance of carbon membranes in the future. By understanding the available methods, one can choose and optimize the best technique during the fabrication of carbon membranes. Furthermore, areas of future potential in carbon membrane research for gas separation were also briefly identified.
