In the present study, we fabricate a hydrophobic film using a roll-to-roll technique capable of large-area continuous production and examine the film’s applicability to solar panels. The hydrophobic film was fabricated using a polyurethane-acrylate (PUA)-based UV-curable material, which has high optical transmittance and high releasability. The roll-to-roll system used in this study was custom manufactured to transfer micro-patterns of 20 μ m in size onto the PUA-based film. In addition, a UV irradiation device was attached to the system to enable production of the hydrophobic film at a rate of 150 mm min -1 . Through experiments, we confirmed that attaching the fabricated hydrophobic film not only enabled surface self-cleaning on the solar panels, but also ensured stable solar power generation. Thus, the hydrophobic film can be applied to installations that require external periodic cleaning and management, such as the exterior walls of buildings and solar panels...

批量生产聚氨酯丙烯酸酯类疏水膜：太阳能设备的下一代保护层

在本研究中，我们使用能够大面积连续生产的卷对卷技术制造疏水膜，并研究了该膜在太阳能电池板上的适用性。使用具有高透光率和高剥离性的基于聚氨酯-丙烯酸酯（PUA）的UV可固化材料制造疏水膜。本研究中使用的卷对卷系统是定制制造的，可将尺寸为20μm的微图案转印到基于PUA的薄膜上。另外，将紫外线照射装置附接​​到该系统以使得能够以150mm min -1的速率生产疏水膜。通过实验，我们证实附着的疏水膜不仅可以使太阳能板上的表面自清洁，而且可以确保稳定的太阳能发电。从而，
