    Cyclic voltammetry and XPS studies of poly (aniline-co-3-aminophenol) حسب Waware, Umesh Somaji

    منشور في 2022
    "…In the electrochemical study, the copolymers differ from PA in the single-electron oxidation and reduction, reversibly at various scan rates ranging from 20 to 50 mV. The current density decreases from PA-co-3-AP20 to PA-co-3-AP80 by increasing the loading weight percentage of 3-aminophenol in the polymeric backbone. …"

    Effect of surfactant and electron treatment on the electrical and thermal conductivity as well as thermal and mechanical properties of ehylene vinyl acetate/expanded graphite compo... حسب Sefadi, Jeremia Shale

    منشور في 2015
    "…The thermal conductivity linearly increased with EG content, and this increase was more pronounced in the case of SDS-EG, but decreased after EB irradiation. The thermal properties were little influenced by EB irradiation, while better polymer–filler interaction and better filler dispersion as a result of SDS treatment, and the EB irradiation initiated formation of a cross-linked network, had a positive effect on the tensile properties.…"
