【摘要】 系统地研究了极化条件、热历程、增塑作用等与聚氯乙烯薄膜压电性的关系,并且讨论了聚氯乙烯薄膜压电性对时间的稳定性。研究结果表明,极化聚氯乙烯薄膜的压电应变常数d₃₃值为2.1×10^-12C/N,压电电压常数g₃₃达到73.9×10^-3V·m/N,与经典的压电材料石英晶体的压电性相当。更多还原

【Abstract】 The connections of the piezoelectricity in poly （vinyl chloride） films with the polarizing conditions, thermal history and plasticization are systematically studied, and also the stability of the piezoelectricity in poly （vinyl chloride） films is disscussed in this paper. The results show that the piezoelectric constant d₃₃ for polarized poly （vinyl chloride） film is up to 2.1×10^-12 C/N, and g₃₃ to 73.9×10_-3 V.m / N which correspond to the values for quartz.更多还原
