DOI: 10.1016/j.cherd.2019.09.011
Abstract: Abstract Carbon molecular sieving (CMS) membranes with enhanced separation performance were prepared from polyimide incorporated with attapulgite (ATP). The membranes were characterized by thermogravimetry, Fourier transform infrared spectroscopy, scanning electron microscope and X-ray diffraction. The… read more here.

DOI: 10.1016/j.memsci.2018.01.021
Abstract: Abstract This article considers a previously overlooked feature in carbon molecular sieve (CMS) membranes that we term a “hyperskin” present at the outermost region of dense CMS selective layers. Such a feature with much lower… read more here.

DOI: 10.3390/membranes11070482
Abstract: Carbon molecular sieve (CMS) membranes have been developed to replace or support energy-intensive cryogenic distillation for olefin/paraffin separation. Olefin and paraffin have similar molecular properties, but can be separated effectively by a CMS membrane with… read more here.

DOI: 10.3390/membranes8040134
Abstract: Carbon molecular sieve (CMS) membranes are novel materials derived from the pyrolysis of the polymeric precursors and have a well-developed ultra-microporous structure that can separate small gas pairs with minor difference in diameter, and thus… read more here.
