Abstract
En 中文
• Polymer swelling was used to positively enhance the separation performance of MMMs for the first time. • The time-dependent C3H6 and C3H8 permeation behavior in Zn-bzc-2CH3/XLPEO MMMs was investigated. • The relationship between diffusion path, transport resistance distribution, and polymer swelling degree was discovered. • Deep separation of C3H6 and C3H8 was achieved under optimized polymer swelling degree.
