Impedance spectroscopy of polymer-ceramic composites

Abstract

Polymer-ceramic composites from a new class of construction and functional materials of great potential applications in having combined hardness and stiffness of ceramics along with flexibility, elasticity, low density, and higher breakdown strength of polymers and hence are being increasingly harnessed for their specific dielectric, ferroelectric, piezoelectric, piezoelectric, electro-optic, as well as superconducting properties in micro-devices. The charge transport mechanism in polymer-ceramic composites is a longstanding problem. Alternating Current Impedance Spectroscopy (ACIS) is faind to be a valuable experimental tool for the understanding of the phenomenon of the charge transport in micro-and nano composites. Keywords: polymer composite; impedance spectroscopy; polymer; complex resistance; electric field; relaxation time; phase shift angle.
