Hello:

Overall, your article contributions add significant detail to the Wikipedia article. I would see if there are appropriate images to add to the written content. The sources used are varied and have all the information included in your article contribution. These was one stylistic piece in the lead section I am not sure is appropriate for Wikipedia. Specifically, I’m not sure the parenthetical statement “permeability must be sacrificed for selectivity and vice-versa” is appropriate in parentheses. Consider creating a separate clause or sentence for that information, as it is vital to stipulate performance bounds for polymeric membranes. The section on perovskite membranes seemed a bit too specific for the contents of Wikipedia, and there was only one source, so it seemed like the description of a specific case study. If other studies have been conducted using this material in gas separation would make the section more encyclopedic.
