Abstract

Abstract: The last advances on the application of INCA (Ionomer Nc Analysis) methodology for a better understanding of perfluorinated ionomers are reported and discussed. It was found that INCA is a very suitable technique for the determination of the melting temperature (Tm) of un-crystallized and semi-crystalline perfluorinated ionomers. Furthermore, for these determinations, it is even more precise than dynamic mechanical analysis, a method essentially developed for polymers in which the water-uptake is negligible. Of interest, it is the information that INCA methodology gives on the phenomenon of the water-uptake memory of perfluorinated ionomers. Highlights: Last advances on the application of INCA (Ionomer Nc Analysis) methodology. Simple determination of the melting temperature (Tm) of un-crystallized and semi-crystalline perfluorinated ionomers. All the Nc/T plots obtained have about the same slope (0.08).
