Various properties of electrowetting such as reversibility, reproducibility and mobility have been investigated experimentally. A conductive water drop on a thin hydrophobic film of amorphous fluropolymers coated on the counter electrode showed unexpectedly the poor reversibility under the discontinuous voltage, so called the contact angle hysteresis. The hysteresis could not been completely suppressed by inserting additionally a thick parylene-C film which has the high dielectric constant and no pinholes. However, both the reversibility and the reproducibility have been enhanced under the continuous voltage starting from the highest absolute electric potential.
人们已经通过实验研究了电润湿的各种特性，如可逆性、可重复性和迁移率。在反电极上涂覆的非晶含氟聚合物薄疏水膜上的导电水滴，在不连续电压下，即所谓的接触角滞后现象，显示出出乎意料的较差可逆性。额外插入具有高介电常数且无针孔的厚聚对二甲苯-C膜，并不能完全抑制这种滞后现象。然而，从最高绝对电势开始施加连续电压时，可逆性和可重复性都得到了增强。
