Abstract

Hybrid POSS^® Octa Amic Acid-Matrimid^® nanocomposite membranes have been successfully fabricated. The study shows that the nano-sized POSS^® could be distributed uniformly over the Matrimid^® matrix with an intimate polymer-particle interface. This is presumably ascribed to the existence of intermolecular hydrogen bonding between the carboxylic groups of POSS^® and Matrimid^®. The excellent dispersion of POSS^® with eight carboxylic functional groups each moiety provides a high-density ionic binding platform for the introduction of Zn²⁺, which is the engine of the facilitated transport to some specific gases. The best gas separation performance is observed for the hybrid POSS^®-Matrimid^®-Zn²⁺ nanocomposite membrane (20wt% POSS^®-Matrimid^®-0.3M ZnCl₂), in which, the selectivity of CO₂/CH₄ and O₂/N₂ increases by 70% and 30%, respectively, when compared with untreated nanocomposite membrane (20wt% POSS^®-Matrimid^®).
