Abstract
One or more embodiments relates to a method of synthesizing a cross-linked polymer blend material suitable for gas separation applications. The method includes providing a blend of one or more polyphosphazene polymers containing vinyl groups (—CH═CH2); and providing a polysiloxane containing reactive silicon-hydrogen (Si—H) bonds. Additionally, the method includes cross-linking the polyphosphazene polymer blend and the polysiloxane through a hydrosilylation reaction, forming the cross-linked polymer blend material.
Claims22
A method of synthesizing a cross-linked polymer blend material suitable for gas separation applications, the method comprising:
- providing a blend of one or more polyphosphazene polymers containing vinyl groups (—CH═CH2);
- providing a polysiloxane containing reactive silicon-hydrogen (Si—H) bonds;
- and
- cross-linking the polyphosphazene polymer blend and the polysiloxane through a hydrosilylation reaction, forming the cross-linked polymer blend material.
A method of separating a gas from a gas mixture, comprising:
- contacting a cross-linked polyphosphazene-polysiloxane polymer with the gas mixture comprising at least one of CO2, N2, O2 and CH4;
- and
- allowing at least a portion of the gas mixture to permeate and pass through the polymer, whereby at least a portion of the CO2/N2, or CO2/CH4, or O2/N2 is separated from the gas mixture.
