Understanding the mechanism of the stability and decay of surface electrostatic charges in different liquid environments is critical for the reliability of devices based on electrostatic functions or preventing the damage from electrostatic charge accumulation. In this work, the influences of surface electrostatic charges in polar and protic (Ethanol and Water), polar and aprotic (Tetrahydrofuran and Chloroform), and non-polar and aprotic (Benzene and Hexane) liquids have been investigated. Results prove that ionization in liquid or polarity of the liquid molecules can determine the electrostatic charges neutralization, and adding small amount of matter (1% Vol) that can ionize in non-polar and aprotic liquids can avoid the electrostatic charges accumulation. Moreover, air-bubble-structured electret is designed to improve the water-against ability for surface electrostatic charges.

了解不同液体环境中表面静电荷的稳定性和衰减机理对于基于静电功能的设备的可靠性或防止静电荷积累造成的损坏至关重要。在这项工作中，研究了极性和质子（乙醇和水），极性和非质子（四氢呋喃和氯仿）以及非极性和非质子（苯和己烷）液体中表面静电电荷的影响。结果证明，液体中的电离或液体分子的极性可以确定静电荷的中和作用，添加少量可以在非极性和非质子液体中电离的物质（1％体积）可以避免静电荷的积累。此外，
