P(VDF-TrFE)聚合物在声发射传感器方面的应用
|
Abstract:
为了研究聚(偏氟乙烯-三氟乙烯) (P(VDF-TrFE))聚合物对声发射信号接收及传感性能的影响，采用流延法制备了P(VDF-TrFE)薄膜，系统地比较了经不同退火温度处理的P(VDF-TrFE)聚合物的结晶度和电学性能，并建立了一种快速测试P(VDF-TrFE)聚合物薄膜声发射响应性能的方法。结果表明：随退火温度升高，P(VDF-TrFE)聚合物结晶度和介电常数逐渐增加。在电场200 MV/m下，经150℃退火处理的薄膜压电应变常数最大，其值为24.5 pC/N。提高退火温度同样有利于薄膜的声发射传感性能，其接收信号峰幅值可达72.2 mV。这为PVDF基氟聚合物在声发射传感器方面的应用提供了参考。
In order to study the effect of poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) copolymer on the acoustic emission (AE) signal receiving and sensing performance, P(VDF-TrFE) films were prepared by solution casting method. The crystallinity and electrical properties of the P(VDF-TrFE) films annealed at different temperatures were systematically compared, and a method for quickly testing the acoustic emission response performance of P(VDF-TrFE) films was established. The results show that the crystallinity and dielectric constant of P(VDF-TrFE) copolymer enhance with the increase of annealed temperature. Under the electric field of 200 MV/m, the piezoelectric coefficient of the film annealed at 150？C is the largest, with a value of 24.5 pC/N. Increasing annealed temperature is also beneficial to the acoustic emission sensing performance of the film, and the peak amplitude of the received signal can reach 72.2 mV. This provides a reference for the application of PVDF-based fluoropolymer in acoustic emission sensors.
