Water electrospray in the cone jet mode was performed by a polymer micro-atomizer. A high aspect ratio dielectric polymer micro-nozzle and an in-plane extractor were proposed to concentrate the electric field at the tip of the micro-nozzle, which prevent electrical discharge caused by the high surface tension of water. The effect of the in-plane extractor was confirmed by electric field simulation and electrospray experiment. A micro-pillar array was also proposed to prevent surface wetting of the polymer micro-atomizer during the electrospray. Water electrospray of the polymer micro-atomizer was operated in a flow rate of 0.15–0.30 ml/h with a voltage of 1.5–3.0 kV, −2.0 kV, and −4.0 kV at water, a guide ring, and a collector, respectively. The key features of the cone jet mode such as Taylor cone, jet, and water micro-droplets were visualized by using nanosecond pulsed laser illumination.

通过聚合物微雾化器以锥形喷射模式进行水电喷雾。为了将电场集中在微喷嘴的尖端，提出了一种高纵横比的介电聚合物微喷嘴和面内提取器，以防止由于水的高表面张力而引起的放电。通过电场模拟和电喷雾实验证实了面内提取器的作用。还提出了微柱阵列以防止在电喷雾期间聚合物微雾化器的表面润湿。聚合物微雾化器的水电喷雾分别在水，导向环和收集器上以0.15–0.30 ml / h的流速，1.5–3.0 kV，-2.0 kV和-4.0 kV的电压运行。圆锥喷射模式的主要功能，例如泰勒圆锥，喷射，
