Abstract

This study goes on with the microstructural and electrical characterization of the films, object of our study, containing hydrogenated poly(butadiene‐styrene) block copolymer (HSBS). Ethylene–propylene terpolymer (EPDM), and a third component, polypropylene (PP), polystyrene (PS), or silica, crosslinked with peroxides and heterogeneously sulfonated. This process pursues the obtaining of materials with high proton conductivity and great dimensional stability, suited for application in a variety of electronic devices. The structural characterization consists of the study of the dynamic mechanical properties of all the samples, before and after the sulfonation, and also the checking of their structure by infrared spectroscopy. The analysis of the electrical properties of the films hydrated is achieved by electrochemical impedance spectroscopy. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 13–21, 2006
