Popis: | LDPE/P4VP films synthesized by in situ sorption and thermal polymerization of 4-vinylpyridine, (4VP), were used for conductivity investigations. The conductivities of swollen films varied from 7×10−6 to 1.21×10−3 S.cm−1 at room temperature depending on P4VP mass increase in the host matrix. For the temperature range of 303–333K the conductivity varied from 7×10−6 to 2.66×10−3 S.cm−1. A comparison between Arrhenius and VTF plots for conductivity measurements showed a best fit for temperature dependence according Arrhenius modified equation. The materials are stable for temperatures below 645 K. |
