摘要
由扫描电镜照片可以看出，分子筛炭膜由一种致密结构和一种由粒子堆积而成的多孔结构所组成，在这些膜结构中，有可能存在两种类型的孔：微孔和大孔。讨论了孔系统、膜的形态结构、和结构缺陷的形成，以及它对膜特性的影响。
Through scanning electron micrograph, it can be seen that the molecular sieve carbon membrane consist of a kind of dense structure and a porous support which correlated with packing of particles. There may be types of porous systems in the membrane structure:micropores and macropores. The formation of porous systems, the morphological structure of membranes and its structure defects, and the influence of the defects on characteristics of the membrane are discussed.
