Abstract

Achieving high water vapor transport while maintaining selective barrier properties in a single material is a crucial property desired in various fields. Breathable protective fabrics is one such area. This study specifically investigates the water vapor transport characteristics and barrier performance of carbon molecular sieve (CMS) membranes for potential applications in breathable protective fabrics. CMS membranes were fabricated by pyrolyzing precursor membranes with a focus on exploring the impact of different pyrolysis temperatures, membrane structures, and polymer concentrations on the properties of such membranes. A series of symmetric and asymmetric Matrimid CMS membranes were synthesized and tested. Samples pyrolyzed at 550 °C with 10% polymer concentration exhibited remarkable water vapor transport capability, outperforming commercial breathable fabrics by a factor of 2.6 despite having 3 orders of magnitude smaller pores. Owing to these small pores, they provide 7.5 times higher protective capacity compared to commercial breathable fabrics, which is comparable to that of the standard vapor impermeable protective material─butyl rubber.

期刊介绍： ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
