中文摘要：

介绍了一种基于高压静电打印技术的工作原理。静电打印头结构是由喷孔结构和电极结构复合而成。施加2.5-3.5kV的脉冲电压驱动液滴产生,所得的液滴直径比传统静电喷射方法更小的液滴,直径为1991-201.6nm。同时,考察在2.8kV,3.0kV,3.2kV和3.4kV四种脉冲电压条件下幅值下幅值大小对液滴大小的影响情况,实验结果表明随着脉冲幅值的增大液滴逐渐减小结论。

英文摘要：

The principle of printing technique basing on the high - voltage electrostatic is introduced. The structure of electrostatic print head was made up of the orifice and the eletrodes. The pulse voltage about 2.5kV to 3.5kV is applied to make droplets come into being, which diameters from 1991nm to 201.6nm are smalller than that from traditional electrostatic printing. The effects of 2.8kV, 3.0kV, 3.2kV and 3. 4kV pulse voltages on the sizes of droplets are also discussed, then the conclusion that the sizes of droplets decrease with the pulse voltages increasing is drawn.
