Enhanced functional properties of soft polymer-ceramic composites by swift heavy ion irradiation

Abstract

Physical and chemical properties of soft polymer-ceramic composites with 50 MeV swift heavy, Li3+ ion irradiation have been studied. Solution-casting technique has been employed to synthesize free standing, flexible composite films of ferroelectric polymer PVDF and ferroelectric ceramic BNBT mixture with 0-3 connectivity. However, only 35wt.% ceramic is chosen for the study as it showed highest dielectric constant and enhanced ferroelectric property without irradiation. The effect of ion irradiation on the structural, microstructural, morphological, dielectric and ferroelectric properties of this particular composition have been systematically investigated and conclusion was drawn. The mechanism for the enhancement of electro active β-phase due to swift heavy ion irradiations has been discussed and has been well correlated with the ferroelectric and dielectric properties.
