Over the last several decades, the incorporation of inorganic nanomaterials into polymer matrix has been studied to improve polymer properties and functional performances. Carbon nanotubes (CNTs) have good mechanical and electrical properties, leading to potential use in a wide range of applications such as sensors, composites, catalyst supports, and gas separation membranes. CNT/polymer nanocomposites have been attracted considerable attention due to their unique mechanical, electrical, and thermal properties. CNTs usually have specific interactions with polymer matrix resulting from the nanoscale structure and extremely large interfacial area of CNTs. CNTs would be considered as possible selective nanopores in polymer membranes, if properly tuned. In this work, we prepared CNT/polymer nanocomposite membranes using the various compositions of CNT and polyimide. We will discuss the effect of pore diameter of CNT and the CNT morphologies on the gas transport properties in detail. |
