在本文中，商业相关背板的特征在于其材料和层压结构以及基本光学和机械性能。选择各种多层背板材料，并通过光学显微镜、拉曼光谱、红外光谱（FTIR-ATR）、热重分析（TGA）、差示扫描量热法（DSC）、紫外可见近红外光谱（UV/VIS/NIR）和单调拉伸测试进行分析。通过拉曼光谱、红外光谱和DSC，鉴定了各层的聚合物材料。此外，对于热塑性乙烯乙酸乙烯酯共聚物（EVA）层，显示使用了三种不同的乙酸乙烯酯（VA）含量。通过TGA检测到无机填料和颜料的含量为约6%(m)至约20%(m)。白色颜料背板的半球形太阳反射率范围为0.695至0.838。在基于聚氟乙烯的多层结构中发现了最高的杨氏模量，而在基于聚酰胺的结构中检测到了最低的值。 (C) 2015 Elsevier B.V. 保留所有权利。
In this paper commercially relevant backsheets are characterized as to their material and laminate structure and basic optical and mechanical properties. Various multilayer backsheet materials were selected and analysed by optical microscopy, Raman spectroscopy, infrared spectroscopy (FTIR-ATR), thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), ultra violet visible near infrared spectroscopy (UV/VIS/NIR) and monotonic tensile testing. By Raman and infrared spectroscopy and DSC the polymeric materials of the various layers were identified. Furthermore it was shown for the thermoplastic ethylene vinylacetate copolymer (EVA) layers that three different vinylacetate (VA) contents were used. By TGA a content of inorganic fillers and pigments from about 6%(m) to approximately 20%(m) was detected. The hemispherical solar reflectance of the white pigmented backsheets was ranging from 0.695 to 0.838. The highest Young's modulus was found in polyvinylfluoride based multilayers while the lowest values were detected for polyamide based structures. (C) 2015 Elsevier B.V. All rights reserved.
