Other Carbon-Based Membranes
Recently Holt et al. developed carbon nanotube (CNT) membranes whose pore size s were smaller than 2 nm by using a microelectro-mechanical system (MEMS) -compatible fabrication process and showed gas and liquid permeation rates orders of magnitude higher than the calculated values based on either Knudsen or Poiseiulle flow mechanism, due most likely to extreme smoothness of the inner wall of carbon nanotubes. This proved the theoretical prediction made earlier by the molecular dynamics simulation. Several attempts have been made since the work of Holt et al. to fabricate the carbon nanotube membrane in a larger scale aiming at industrial applications. There have been other developments in carbon related membranes particularly in the field of nano-technology . One of such developments is carbonization of nanofibers for the membrane adsorption process. Carbon particles and especially carbon nanoparticles have also been incorporated in the mixed matrix membranes to enhance gas separation performance of the membranes.
