研究了在柔性聚合物基底上制备的偏氟乙烯低聚物薄膜在机械弯曲作用下的铁性能和压电性能。观察到聚酰亚胺基板的矩形电-位移-电场滞后曲线，残余极化和矫顽力电场在曲率半径低至10mm的一维弯曲时不受影响。测量了弯曲和恢复过程中产生的压电电荷，发现压电电荷与曲率半径有关。这些结果表明，在柔性非易失性存储器和曲率传感器中使用偏氟乙烯低聚物是可能的。
The ferro- and piezoelectric properties of vinylidene fluoride oligomer thin films fabricated on flexible polymer substrates were investigated under mechanical bending. Rectangular electric-displacement–electric-field hysteresis curves were observed for a polyimide substrate, and the remanent polarization and coercive electric field were unaffected on one-dimensional bending with a radius of curvature down to 10mm. The piezoelectric charge generated by the bending and restoring process was measured and found to be dependent on the radius of curvature. These results indicate the possibility using the vinylidene fluoride oligomer in the construction of both flexible nonvolatile memories and curvature sensors.
