New Developments in Gas Separations: PIMS, TR Polymers, Polymer Supported MOFs and Porous Organic Sorbents
15:30 - 16:00
Level 0, between bld. 4 and 5
In this presentation we will develop the main research lines carried out in the group of Polycondensation and Polymeric Membranes of the Institute of Polymer Science and Technology, especially those related with gas separation membranes and gas sorbents.
The presentation will be divided in four main topics:
(1) Synthesis of new polymers with high rigidity and high FFV based on conventional monomers. Combination of pyromellitic dianhydride and contorted diamines.
(2) Synthesis of new monomers as precursors of thermally rearranged (TR) polymers. Study of the influence of the chemical structure on the process of thermal rearrangement and development of new low cost monomers.
(3) Modification of high performance polymers to improve the homogeneous growing of thin MOF films in the surface of membranes. Attempts to avoid the growing of undesired large crystals.
(4) Preparation of new microporous materials based on an innovative synthetic method, based on electrophilic aromatic substitution reactions. To do that, we have made to react ketones with electron-withdrawing groups, such as isatine, and contorted aromatic molecules with high electronic density in the aromatic rings, like trypticene, using a superacid medium. These reactions yield amorphous crosslinked materials with a very high percentage of microporosity and CO2 sorption.
