摘要：

This paper focuses on the preparation and characterization of a new type of polyimide magnetic inorganic-organic hybrid membranes and analysis of their potential application in synthetic air enrichment with oxygen. These hybrid membranes were based on linear (ODPA-MDA) and hyperbranched (ODPA-MTA) polyimide matrix and NdFeB magnetic microparticles. It was conducted the characteristics of their gas permeation, magnetic, thermal, mechanical and rheological properties. It was stated that the application of polyimides as polymer matrices and magnetic powders as fillers (especially with higher content and lower particle size) allowed to create unusual hybrid membranes with the improved gas transport and separation properties (coefficient's P, D, S and alpha), mechanical and rheological parameters (E, G', G'' and tan d) and the excellent thermooxidative stability. All this will allow for their future potential application in the separation of air. (C) 2017 Elsevier B.V. All rights reserved.
