In this work, the local current-voltage characteristics of nanocomposite phase boundaries in the form of a poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) (70/30) matrix filled with conductive polyaniline (PANI) particles are studied by conductive atomic force microscopy. At negative external bias voltages, these dependencies are shown to have an interval with a negative differential resistance. This fact is caused by the switching of ferroelectric polarization of individual nanocrystallites PVDF-TrFE located near the phase boundaries in the amorphous matrix volume. The obtained results confirm assumptions about the memristive properties of the investigated nanocomposites.

相界PVDF-TrFE(70/30)/PANI纳米复合材料的电流-电压特性

在这项工作中，通过导电原子研究了填充有导电聚苯胺（PANI）颗粒的聚（偏二氟乙烯-三氟乙烯）（PVDF-TrFE）（70/30）基体形式的纳米复合材料相边界的局部电流-电压特性。力显微镜。在负外部偏置电压下，这些相关性显示为具有负差分电阻的间隔。这一事实是由位于非晶基质体积中相边界附近的单个纳米微晶 PVDF-TrFE 的铁电极化的切换引起的。获得的结果证实了关于所研究的纳米复合材料的忆阻特性的假设。
