dc.description.abstract |
Hybrid composites with expanded graphite (ExGr) as the second conducting
component in PPS-7 wt% graphite have been prepared by powder mixing method. The
percolation threshold in the hybrid composites lies at 0.25wt% ExGr. Addition of 1 wt%
ExGr in PPS-7 wt% graphite increases through plane conductivity by six orders
compared to 0 wt% ExGr addition. The ac conductance study reveals that insulatorsemiconductor
transition occurs at higher loading of ExGr in hybrid composites. For
0.75 wt%ExGr addition in PPS-7 wt% graphite, the charge transport occurs by hopping
mechanism. Expanded graphite sheets predominantly occupy intergraphite spaces in
hybrid composites. Impedance measurement has been carried out to evaluate interfacial
capacitance which increases with enhanced ExGr loading. The composites are
characterized by SEM, Impedance etc. |
