用改进的介电松弛谱仪(精度2‰)测定了VDF(52)/TrFE(48)和VDF(47.5)/TrFE(47.5)/HeFP(5)在-120—140℃,10~(-2)-10~4Hz 范围的复数介电常数。介电松弛研究结果显示5mol%的HeFP 导致三元共聚物T_c 下降(30℃),非晶松弛强度减弱,T_g 降低(3℃),并引起局域松弛活化能升高(10.1kJ/mol),松弛时间增长。
The complex dielectric constants of VDF(52)/TrFE(48)andVDF(47.5)/TrFE(47.5)/HeFP(5)in the range of-120-40℃,10~(-2)—10~4 Hz were measured bythe improved dielectric relaxation spectrometer.Because 5mol% vinylidene fluoride(VDF)wassubstituted by hexafluoro-p
