Polyimides and their derivatives for gas separation applications

PDF Version Also Available for Download.

Description

High performance polymers are of interest for high temperature gas separations, especially for the sequestration of carbon dioxide. A new family of high performance imide polymers (VTEC, RBI Inc.) has been identified as a material class containing the potential building blocks needed for a successful membrane capture material. The VTEC polyimides possess the desired thermal properties (up to 500 °C) and are robust and flexible even after multiple thermal cycles (up to 400 °C). A critical variable when working with the glassy polymers is their moisture content. It has been found that water entrapped within the polymer matrix (either as ... continued below

Description

High performance polymers are of interest for high temperature gas separations, especially for the sequestration of carbon dioxide. A new family of high performance imide polymers (VTEC, RBI Inc.) has been identified as a material class containing the potential building blocks needed for a successful membrane capture material. The VTEC polyimides possess the desired thermal properties (up to 500 °C) and are robust and flexible even after multiple thermal cycles (up to 400 °C). A critical variable when working with the glassy polymers is their moisture content. It has been found that water entrapped within the polymer matrix (either as hydration molecules attached to salts in the polymer, left over solvent, or physisorbed) can also cause the polymer to change dramatically. Additionally presence of molecular water in the polymer’s void volume has been validated through Positron Annihilation Lifetime (PAL) spectroscopy. In this presentation, polymer characterization and gas-separation testing results will be discussed.
