摘要
本文用红外光谱及压电常数方法研究了偏氟乙烯-四氟乙烯共聚物在高压直流电场下,γ晶型向β晶型的固相转变。同时用动态力学方法、介电损耗测试法及压电常数方法研究了样品的松弛现象。
The solid transformation from γto β crystal induced by high electric fields werestudied by infrared spectroscopy and piezoelectric measurements. The relaxations inthe samples were studied by dynamic mechanical, dielectric and piezoelectricmeasurements.
