Insights into the development of carbon molecular sieve membranes from polymer blends for gas separation: A review

Abstract

This study analyzes carbon molecular sieve membranes (CMSM) derived from the pyrolysis of polymer blends. While many studies have focused on modifying polymeric precursors to enhance CMSM performance, blending polymers provides a cost-effective method for creating materials with unique characteristics. However, the literature on CMSM derived from polymer blends is limited. This paper offers background information on CMSM structure and examines parameters affecting their gas separation performance, including the properties of polymeric precursors, blend composition, and pyrolysis conditions. Additionally, it provides valuable insights into unexplored blends for CMSM development, as well as methods to improve the miscibility of polymer blends.
