Abstract
The use of nanoporous polymeric systems for applications such as fuel cell proton exchange membranes, nanoscale templated particle synthesis, water purification, redox flow battery membranes, and sensor material has been the subject of intense interest. Previous work in our lab has shown the synthesis of a nanoporous chemically cross-linked epoxy amine system with tunable pore size. The alteration of the inherent hydrophobic character of the porous system into a hydrophilic one is an essential step towards their further use in various applications. To achieve this, sulfonation of polymeric systems is an attractive route to simultaneously incorporate hydrophilicity, proton conductivity and increased strength. This report outlines the use of sulfonation as a first step in modifying pore chemistry for incorporating hitherto inaccessible properties. Our work discussed outlines the solid-state sulfonation carried out on the aromatic rings in the nanoporous epoxy-amine system in order to modify the pore interface. Subsequent characterization using spectroscopic and thermogravimetric analysis as well as water uptake measurements were done in order to confirm the presence of sulfonic acid group added to the polymeric system.
