Optionally, the materials of the present invention are composite materials comprising both polymerized and non-polymerized RTILs. The RTIL polymer is formed from polymerized RTIL cations typically synthesized as monomers and polymerized in the presence of the non-polymerized RTIL cations to provide a solid composite material. The non-polymerized RTIL cations are not covalently bound to the cationic polymer but remain as free cations within the composite material able to associate with charged subunits of the polymer. These composite materials are useful in catalysis, gas separation, and antistatic applications.

  • Publication number: 20150147668
    Abstract: A sweep membrane separator includes a membrane that is selectively permeable to a selected gas, the membrane including a retentate side and a permeate side. A mixed gas stream including the selected gas enters the sweep membrane separator and contacts the retentate side of the membrane. At least part of the selected gas separates from the mixed gas stream and passes through the membrane to the permeate side of the membrane. The mixed gas stream, minus the separated gas, exits the sweep membrane separator. A sweep gas at high pressure enters the sweep membrane separator and sweeps the selected gas from the permeate side of the membrane. A mixture of the sweep gas and the selected gas exits the sweep membrane separator at high pressure. The sweep membrane separator thereby separates the selected gas from the gas mixture and pressurizes the selected gas.

  • Publication number: 20150096442
    Abstract: A composite membrane for separations includes a fabric with a non-woven array of intermingled carbon nanotubes, and a dopant incorporated with the fabric to form a non-porous, permeable composite. The composite membrane may be used to separate a target gas from a liquid by mounting the composite membrane in a housing chamber, and conditioning a permeate side of the chamber to establish a driving force for the target gas across the non-porous, permeable composite membrane.
