Crystallization behaviors and related dielectric properties of semicrystalline matrix in polymer-ceramic nanocomposites

Crystallization behaviors and related dielectric properties of semicrystalline matrix in polymer-ceramic nanocomposites have been systemically investigated by using P(VDF-TrFE) 70/30 mol.% as Ba0.5Sr0.5TiO3 nanoparticles filler. It is found that due to the presence ceramic nanofiller, there are two types crystals formed matrix: one on surface other polymer. The former favors all-trans ? phase interaction between chains surface. later has defects result low-temperature phases: well-ordered less-ordered (i.e. ?? phase). conformation it a lower permittivity than phase. proportion ?’ decreases with increasing content only can be observed higher 35 vol%. These results were reflected confirmed DSC analyses properties.
