Design and Development of high performance multi-purpose gas separation membranes based on interpenetrated polymer blend networks

摘要

Membrane-based gas separation is increasingly gaining attention as a promising technology in various sectors of the industry. Despite the competitive advantages offered by membranes especially in terms of footprint, capital cost and energy efficiency, further progresses are required in order to well position this technology as a viable alternative to the counterpart established processes. This presentation will showcase our efforts in the identification and exploration of the key approaches and strategies to overcome the shortcomings and to address the challenges that have impeded the widespread application of gas separation membranes. We will demonstrate the successful implications of blending high performance polymers for the fabrication of advanced membranes with tunable transport properties and separation performance. The effect of variation in composition on miscibility and microstructure, gas permeability and selectivity of blend membranes prepared from polyimides and PBI is investigated.
