The work presents the results of investigations of electrets formed according to the liquid method. This method utilizes transmission of electric charge from conductive liquid to dielectric surface. Electrets were made of poliester foil "Hostaphan". Various liquids such as acetone, ethanol, Ringer solution and distilled water were used for charging. It was established that surface densities of electret charge formed by Ringer solution and acetone are about from 15 to 20 nC/cm2, whereas those formed by ethanol and distilled water from 5 to 10 nC/cm2. These electrets are characterized by big stability of charge and their survival time is about 100 years. Deelectrization of electrets in liquids that were formerly used for formation was also performed. It appeared that the survival time of the samples after deelectrization was several times longer than the survival time of electrets. The longest survival time have samples formed by ethanol and deelectrized by Ringer solution (about 10(9) years).
该研究展示了根据液体法形成的驻极体的研究结果。此方法利用电荷从导电液体传输至介电表面。驻极体由聚酯薄膜“Hostaphan”制成。使用了各种液体，如丙酮、乙醇、林格溶液和蒸馏水进行充电。结果表明，由林格溶液和丙酮形成的驻极体电荷表面密度约为15至20 nC/cm²，而由乙醇和蒸馏水形成的表面密度为5至10 nC/cm²。这些驻极体的特点是电荷稳定性高，其存活时间约为100年。还对曾用于形成驻极体的液体中的驻极体进行了去电处理。结果发现，去电后样品的存活时间比驻极体的存活时间长几倍。由乙醇形成并经林格溶液去电的样品存活时间最长（约10⁹年）。
