  • Preparation and characterisation of solution-cast Nafion membrane
    Publication

    Nafion is a commercial name for a perfluorosulfonic polymer, which has been developed in 1962 by Dupont de Nemours. This polymer consists of a polytetrafluoroethylene backbone and regular spaced long perfluorovinyl ether pendant side chains terminated by a sulfonate ionic group. These sulfonate groups are responsible for cation-exchange properties of Nafion. Thanks to the ion-exchange properties, water permeability, good chemical,...

  • Polimerowe czujniki wilgotności
    Publication

    W pracy przedstawiono przegląd rozwiązań konstrukcyjnych elektrycznych czujników wilgotnosci z filmem polimerowym. Opisano właściwości metrologiczne pojemnościowych i rezystancyjnych czujników wilgotności wraz z najczęściej stosowanymi w nich materiałami polimerowymi. Zaprezentowano również najnowsze próby syntez polimerów, prowadzące do uzyskania trwałych czujników o wysokiej czułości.

  • OPTIMIZATION OF NASICON PREPARATION METHOD

    Nasicon is a solid conductor which has an ability to conduct Na+ ions and it is used in solid gas sensors. In this article a method of Nasicon preparation appropriate for gas sensing application by solgel technique is presented. Influence of the fabrication process parameters on properties of obtained samples was determined. Results of X-Ray diffraction, density, porosity, conductivity, and activation energies measurement are presented.
