    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... by Sefadi, Jeremia Shale

    Published 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.…”
