Architecturing Nanospace via Thermal Rearrangement for Highly Efficient Gas Separations
Thornton, Aaron W.,Doherty, Cara M.,Falcaro, Paolo,Buso, Dario,Amenitsch, Heinz,Han, Sang Hoon,Lee, Young Moo,Hill, Anita J. American Chemical Society 2013 JOURNAL OF PHYSICAL CHEMISTRY C - Vol.117 No.46
<P>The ability to monitor free volume formation during space-making treatments is critical for the ultrafine tuning of nanospace for efficient gas separation. Here, investigating the polymer thermal rearrangement using synchrotron in situ small-angle X-ray scattering for the first time and combining this information with transport theory, we elucidate the evolution of nanospace features in polymer-based gas separation membranes. The proposed nanospace monitoring technique encompasses the structure–property relationships, therefore offering a powerful tool for tuning the polymer properties for particular gas-related clean energy applications. These results demonstrate that the fine control of the nanospace dimension and magnitude leads to a drastic improvement in gas separation performance above any material to date.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2013/jpccck.2013.117.issue-46/jp410025b/production/images/medium/jp-2013-10025b_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp410025b'>ACS Electronic Supporting Info</A></P>
