Abstract
Continuing interest in polymer electrolyte membranes has been fuelled by their potential use in fuel cells, lithium batteries and electro chromic displays [1-3]. A number of different materials have been developed with varying levels of success. One straightforward insight in these types of materials is that hydrophilicity and hydrophobicity are usuallydirectly proportional to proton conductivity and material strength, respectively [4]. In addition, dimensional stability can also be maintained by the incorporation of cross-links within the polymeric system resulting in the fixation of nanosized ion transport channels [5]. Hydrophilicity in such networks is usually incorporated by sulfonic acid moieties in the polymerization process or by a post-sulfonation procedure [1]. This work discusses the control of proton conductivity, porosity, and dimensional stability of a free radical co-polymerized nanoporous thermosetting system synthesized in a one-step procedure. Initial characterization has shown ionic conductivity in the same order of magnitude as commercial Nafion 117.
