设计和开发柔性电子产品需要对可用于制造设备的基板进行彻底的研究。在这里，我们提出了一个实际的研究各种重要的基板：聚对苯二甲酸乙二醇酯（PET），其热稳定（HS）的衍生物，HS-PET，和聚萘二甲酸乙二醇酯（PEN）塑料绝缘膜;铟锡氧化物（ITO）涂层的ITO/PEN和ITO/PET透明导电膜;刚性ITO/玻璃和FTO/玻璃基板;不锈钢和钛箔。我们对这些基板进行了一系列测试，这些测试实际上是在器件制造过程中进行的，以确定它们的光学、机械柔性（在不同类型的拉伸和压缩应力弯曲下，有和没有PEDOT：PSS导电聚合物层）、耐溶剂性、对温度处理的稳定性（导电性和变形）以及对UV照射的稳定性。我们强调问题，并提出解决方案，以提高基板的响应。提取的结果和阈值揭示了柔性光电子设计师在确定制造工艺和日常操作下的最终应用时的限制和机会窗口。(C)2011 Wiley Periodicals，Inc.聚合物科学杂志B部分：聚合物物理49：638-648，2011
Designing and developing flexible electronics requires a thorough investigation of the substrates available for the fabrication of devices. Here, we present a practical study on a variety of significant substrates: polyethylene terephthalate (PET), its heat-stabilized (HS) derivative, HS-PET, and polyethylene naphthalate (PEN) plastic insulating films; indium tin oxide (ITO)-coated ITO/PEN and ITO/PET transparent conducting films; rigid ITO/glass and FTO/glass substrates; stainless steel and titanium foils. We put the substrates through a range of tests these actually undergo during device fabrication to determine their optical, mechanical flexibility (under different types of tensile and compressive stress bending with and without a PEDOT:PSS conducting polymer layer), solvent resistance, stability to temperature treatment (conductivity and deformation), and to UV irradiation. We highlight issues and propose solutions to improve substrate response. The results and thresholds extracted reveal limitations and windows of opportunity useful for the designer of flexible optoelectronics in determining manufacturing processes and the final applications under everyday operation.
