Abstract

Abstract : In this work, −SO3 H functionalized BiFeO3 (BFO‐SO3 H) is prepared and its utility toward the development of polymer‐(BFO‐SO3 H) composites is explored in line with silicon carbide (SiC) as third phase conductive filler, which can be used in the field of high performance electrical storage device (HPESD). Surface functionalization plays a vital role to reduce the agglomeration and improve their surface area for better adhesion with the polymer matrix (polyvinylidene fluoride hexafluoro propylene; P(VDF‐HFP)). SiC directly influences the conducting networks of BFO‐SO3 H favoring high electrical properties of the composites. Similarly, the high remanent polarizations of the SiC‐treated composites indicate their enhanced ferroelectric behavior as compared to that of untreated one. Thus the SiC‐treated polymer‐ceramic composites will be more advantageous for HPESD applications than that of untreated one. Abstract : Schematic representation of composite formation and ferroelectric, electrical and dielectric performances of pure polymer and the respective composites.
