recommendations! Published in 2017 at "Journal of Applied Polymer Science"

DOI: 10.1002/app.44564

Abstract: Novel facilitated-transport mixed-matrix membrane (MMM) were prepared through the incorporation of polydopamine (PDA) microspheres into a poly(amide-b-ethylene oxide) (Pebax MH 1657) matrix to separate CO2–CH4 gas mixtures. The Pebax–PDA microsphere MMMs were characterized by Fourier… read more here.
