New membrane strips carbon dioxide from natural gas faster and better
Date:10/11/2007

y. The method used at the Commonwealth Scientific and Industrial Research Organization suggested the hour-glass shape of the pores within the plastic, which are much more consistent in size than in most plastics.

The pores appear and disappear depending on how often the chains of chemicals that make up the plastic move.

The plastic chains move, and as they do, they open up gaps that allow certain gas molecules to wiggle through the plastic, Freeman said.

Freeman and Park intend to learn more about how these mobile pores behave as they develop the TR plastic for commercial purposes.

Park said, These membranes also show the ability to transport ions since they are doped with acid molecules, and therefore could be developed as fuel cell membranes. However, a lot of research still needs to be done to understand gas and ion transport through these membranes.
