The poor thermal insulating building windows, especially single-pane windows, are wasting ∼ 7% of the total energy consumed by the U.S. every year. This paper presents an electrostatic levitation enabled polymer-air multilayer (EPAM) structure as a highly transparent and energy efficient window retrofitting solution for low-income single-pane window users. To provide controllable and stable suspension force between large size compliant polymer films without deteriorating their visual transmittance (Vt) in the multilayer polymer/air structure, corona discharge (CD) was used to induce quasi-permanent charges for non-conductive polymer films, leading to controllable and long-lasting surface electric potential difference between two sides of CD charged films. Liquid-solid contact electrification (LS-CE) was combined with CD to realize precise control of the electrical potential of each side of polymer films. CD + CE treated films can obtain programmable and stable electrostatic forces to form resilient EPAM structures for cost and energy effective window retrofitting purpose. The resilient EPAM retrofitted clear windows can provide U-factor lower than 3 W·m⁻²·K⁻¹, Vt higher than 70%, haze lower than 1.6% at cost lower than $79.7/m², at least 10 times cheaper than double pane windows. The energy saved by EPAM can reach as much as the order of 10⁶ kJ/m² per year. The CD + CE surface potential programming solution also provides a highly repeatable and controllable way for other electrical potential related technologies, such as energy harvesting and storage.

隔热性能差的建筑窗户，尤其是单层窗户，每年浪费美国能源消耗总量的约 7%。本文介绍了一种支持静电悬浮的聚合物-空气多层 (EPAM) 结构，作为一种高度透明且节能的窗户改造解决方案，适用于低收入的单窗格窗户用户。在大尺寸柔顺聚合物薄膜之间提供可控且稳定的悬浮力，而不会降低其视觉透射率 ( Vt) 在多层聚合物/空气结构中，电晕放电 (CD) 用于为非导电聚合物薄膜诱导准永久电荷，导致 CD 带电薄膜两侧的表面电位差可控且持久。液固接触带电（LS-CE）与CD相结合，实现对聚合物薄膜各面电位的精确控制。CD + CE 处理过的薄膜可以获得可编程且稳定的静电力，以形成弹性的 EPAM 结构，以实现成本和节能的窗户改造目的。弹性 EPAM 改装透明窗可提供低于 3 W·m ^-2 ·K ^{-1 的}U 系数，高于 70% 的Vt，低于 1.6% 的雾度，成本低于 $79.7/m ²，至少比双窗格窗户便宜 10 倍。EPAM 节省的能量可以达到每年10 ⁶ kJ/m ^{2 的数量级}。CD + CE 表面电位编程解决方案还为其他电位相关技术（例如能量收集和存储）提供了高度可重复和可控的方式。
