| Abstract: | The ferroelectric switching characteristics of binary blends of an equimolar P(VDF-TrFE) copolymer with PMMA have been investigated, for PMMA contents ranging from 0 to 40 wt. The results were correlated with thermal and dieletric responses of the materials. The data revealed that the ferroelectric reversal polarization follow a Master -response cruve, when considered the crystallinity variations with blending and poling. Thermal treatment and/or poling stabilize the ferroelectric phase, even for the samples with the lowest degree of crystallinity investigated. These results imply that ferroelectric stable domains were formed for all compositions. The blended amorphous phase participates of the establishment of the stable domains. |
