Abstract

Synthesized polyphenylene oxide asymmetric hollow fiber membranes with an outer diameter 500- 600 μm and an inner diameter 200 μm were investigated. The membrane wall structure asymmetry and the outer diffusion layer thickness were determined using atomic force microscopy. The results obtained are important for improving the performance of membrane selective gas separation and enrichment apparatuses for gas mixtures.
