本研究开发了一种基于使用含氟聚合物和二氧化硅纳米粒子的无机-有机纳米复合材料的新型驻极体。 CYTOP®用于制造纳米复合驻极体，它是含氟聚合物的一种。使用分散在甲基乙基酮中的三种二氧化硅纳米颗粒。每种类型的纳米粒子都混合在 CYTOP 中或粘在三层 CYTOP 之间。然后，通过电晕放电方法注入负电荷。纳米复合材料驻极体的初始表面电势高于纯 CYTOP 制成的对照驻极体。此外，这些材料的时间稳定性也优于对照驻极体。然而，由于通过纳米粒子组成的聚集体放电，混合型驻极体的上述性能比粘着型驻极体差。
An A novel electret based on inorganic-organic nano composite using fluoropolymer and silica nanoparticles was developed in this study. CYTOP® is used to fabricate the nanocomposite electret, which is one of fluoropolymer. Three kinds of silica nanoparticles dispersed in methyl ethyl ketone were employed. Each type of nanoparticles was mixed in the CYTOP or stuck between three layers of CYTOP. Then, negative charge was implanted by corona discharge method. The initial surface potential of the nanocomposite electret was higher than that of a control electret made of pure CYTOP. Additionally, time stability of those was also better than that of control electret. However, above mentioned properties of the mix-typed electret was worse than that of stuck-typed electret, because of discharging through aggregates composed of the nanoparticles.
