Carbon molecular sieving membranes are new, high-performance materials for gas separations. The selectivities of these membranes are much higher than those typically found with polymeric materials, and the selectivities are achieved without sacrificing productivity. Ultramicroporous carbon membrane
Carbon-based molecular sieve (CMS) films for gas separation have been deposited on porous Al 2 O 3 disks using hexamethyldisiloxane (HMDSO) by a remote inductively-coupled-plasma (ICP) chemical vapor deposition (CVD) method. The H 2 /N 2 selectivities of the as-deposited films falled into the range
