论文摘要
电晕充电的独立聚合物膜可以在整个薄膜厚度上产生准永久势差,而表面电压的绝对幅度可能对自由电荷高度敏感。为了准确控制电压分布,我们通过将电晕荷兰二苯二甲酸酯膜暴露于各种钠盐溶液中,研究了流动性技术。表面电压和自由电荷密度通过盐浓度,阴离子尺寸和流速调节。电势的偶极成分保持不变。该结果对表面处理,过滤,能量收集,生物侵略和生物感应等具有很大的科学兴趣和技术重要性。
Corona charging a free-standing polymer film can produce a quasi-permanent potential difference across the film thickness, while the absolute amplitude of surface voltage may be highly sensitive to the free charges. To precisely control the voltage distribution, we investigated the flow electrification technology, by exposing corona-charged polyethylene terephthalate films to a variety of sodium salt solutions. The surface voltage and the free charge density were adjusted by the salt concentration, the anion size, and the flow rate. The dipolar component of electric potential remained unchanged. This result has significant scientific interest and technological importance to surface treatment, filtration, energy harvesting, bio-actuation and bio-sensing, among others.
