Pyrolysis or Sintering of Organic Polymers

In the process of phase separation by heat treaunent followed by chemical leaching as reviewed in Section 3.2.5, the final membrane geometry (e.g., plate or tube) is 

To obtain carbon membranes with molecular sieving properties, pore diameters in the range of a few angstroms are required. The associated pyrolysis procedures and post treatments are more involved. This subject will be treated later under section 3.2.10 Molecular Sieving Membranes.
