Abstract

The influence of thermomechanical stress on the conductivity of indium tin oxide (ITO)-coated polycarbonate (PC) films was investigated. PC is the industry's standard material for window panes. ITO coatings on polyethylene terephthalate (PET) films are the main commercially available option; as such, most investigations refer to this combination. The investigations in this study aim to investigate the critical crack initiation strain at different temperatures and crack initiation temperatures for two different coating thicknesses and for a commercially available PET/ITO film for validation purposes. Additionally, the cyclic load was investigated. The results show the comparatively sensitive behavior of the PC/ITO films, with a crack initiation strain at room temperature of 0.3-0.4% and critical temperatures of 58 °C and 83 °C, with high variation depending on the film's thickness. Under thermomechanical loading, the crack initiation strain decreases with increasing temperatures.

摘要

研究了热机械应力对氧化铟锡（ITO）涂层聚碳酸酯（PC）薄膜导电性的影响。PC是窗玻璃行业的标准材料。聚对苯二甲酸乙二酯（PET）薄膜上的ITO涂层是主要的商业可用选择；因此，大多数研究都涉及这种组合。本研究中的调查旨在研究两种不同涂层厚度以及一种市售PET/ITO薄膜在不同温度下的临界裂纹起始应变和裂纹起始温度，以进行验证。此外，还研究了循环载荷。结果表明，PC/ITO薄膜具有相对敏感的行为，室温下的裂纹起始应变为0.3 - 0.4%，临界温度为58℃和83℃，且随薄膜厚度的变化差异很大。在热机械载荷作用下，裂纹起始应变随温度升高而降低。
