Description
技术领域technical field
本发明涉及电极领域，尤其是涉及一种单面双电极和一种电响应材料表面构型的方法。The invention relates to the field of electrodes, in particular to a single-sided double electrode and a method for surface configuration of an electric response material.
背景技术Background technique
目前电极的结构设计比较单一，主要分为单面电极和双面电极两种形式。双面电极不仅制样步骤复杂，而且应用的领域窄，难有突破性的发展，而单面双电极则具有较大的应用潜力。传统的单面双电极，两块电极中间的刻痕是单个矩形，如图1所示。这种结构的电极，刻痕中的电场强度的提升与电场数量的增加，两者是相互矛盾的，如果想要增加电场的面积，则要增大刻痕的宽度，想要达到相应的电场强度，则要施加更强的电压；在一定电压下，如果想要增大电场强度，就要缩小刻痕宽度，这样又会降低电场的面积。单个长条矩形的刻痕，还会使得导电材料的利用率不高，只有边界附近的材料才能发挥较大作用。而对于需要观察电场响应的样品而言，传统的电极单面双电极因电场数量和刻痕形状的限制，不利于观察样品的相应效果。At present, the structural design of electrodes is relatively simple, mainly divided into two types: single-sided electrodes and double-sided electrodes. Double-sided electrodes not only have complicated sample preparation steps, but also have narrow application fields, making breakthrough development difficult, while single-sided double electrodes have great application potential. In the traditional single-sided double-electrode, the notch in the middle of the two electrodes is a single rectangle, as shown in Figure 1. For electrodes with this structure, the increase of the electric field intensity in the notch and the increase of the number of electric fields are contradictory. If you want to increase the area of the electric field, you need to increase the width of the notch to achieve the corresponding electric field. To increase the strength, a stronger voltage should be applied; at a certain voltage, if you want to increase the electric field strength, you must reduce the width of the notch, which will reduce the area of the electric field. A single long rectangular notch also makes the utilization rate of the conductive material not high, and only the material near the boundary can play a greater role. For samples that need to observe the electric field response, the traditional single-sided double electrode is not conducive to observing the corresponding effect of the sample due to the limitation of the number of electric fields and the shape of the notch.
