Dielectric characterization of electromagnetic composite barrier materials with plasma layers on nonwoven fabrics

Dielectric investigation of a conducting fibrous nonwoven porous mat fabricated by a one-step facile electrospinning process

“…This produces a conducting route through amorphous zone of polymer mat driving to the incremental increase of conductivity which in agreement with González-campos et al 36 and Mahendia et al 16 It has been observed that materials exhibit various electrical and dielectric processes like tunnelling or hopping of charge carriers and different polarizations like dipole, electrode, interfacial polarization etc., which can be effectively explained by utilizing Jonscher universal power law. 37,38 In this context, temperature dependent frequency exponent S is the paramount entity to explain the effective charge transport mechanism for the conducting nonwoven mat. Therefore, different models have been recommended to provide information regarding the type of conduction mechanism favourable in the material using the variation of frequency exponent with respect to the temperature.…”
