US Patent:

20160367935, Dec 22, 2016
Filed:

Aug 31, 2016
Appl. No.:

15/253497
Inventors:

- Paris, FR
Madhava Kosuri - Newark DE, US
Tao Li - Garnet Valley PA, US
Dean Kratzer - Warwick MD, US
Raja Swaidan - Bear DE, US
International Classification:

B01D 53/22
B01D 71/02
B01D 71/70
B01D 67/00
B01D 69/08
Abstract:

A method for making a defect-free carbon molecular sieve (CMS) fiber membrane with an enhanced selectivity and aging resistance includes the steps of fabricating the CMS fiber membrane by pyrolyzing a polymer precursor, coating a thin layer of the silicone rubber on the CMS fiber membrane with the silicone rubber solution and drying the coated CMS fiber membrane to remove the organic solvent. The silicone rubber may be a poly(siloxane) containing repeating units of the moiety of the following formula:wherein Rand Reach is independently selected from the group consisting of an H, a C-Caliphatic group, a C-Caromatic group, and a C-Csaturated or unsaturated alkoxy group. The silicone rubber may be PDMS.
