  • Publication number: 20060138043
    Abstract: Thin Film Composite (TFC) membranes are prepared by coating a thin layer of aminated silicon rubber on the surface of highly porous substrate like ultrafiltration membrane, followed by crosslinking with reactive, aliphatic dialdehyde and curing at high temperature. The TFC membranes so prepared have amine functionality making them suitable for varied separation applications in gas separation, vapor permeation, pervaporation and other membrane separation processes.

  • Publication number: 20050006302
    Abstract: The present invention relates to a porous membrane and a process for the preparation of the same by combining two or more additives, wherein said membrane, useful for ultrafiltration, shows excellent combination of high water flux and solute rejection, said method comprising steps of adding two or more additives in organic solvent(s) to obtain a dope solution, stirring the dope solution, adding polymer slowly into the dope solution, stirring the dope solution, degassing the dope solution, removing the undissolved particles to obtain homogeneous dope solution, casting the homogeneous dope solution, precipitating the cast in a non-solvent, washing the precipitated cast in running water and obtaining the porous membrane having excellent combination of high water flux and solute rejection.
