Stretchable electronic devices fabricated using isobutylene-based materials

未来的电子设备将建立在柔软的聚合物材料上，使其可拉伸，可扭曲和可变形。这种可拉伸性使当前刚性材料无法实现的应用成为可能，例如柔性照明，显示器和太阳能电池;用于机器人的柔软压敏皮肤;以及可层压在皮肤上或植入人体以检测和显示信息的适形生物医学传感器。然而，可拉伸电子产品的研究仅使用可拉伸的硅橡胶材料，这些材料对氧气和水分具有高度渗透性，这会严重降低设备中的有机电子材料并大大缩短设备寿命。 我们的研究旨在通过实施一种不同的可拉伸材料-丁基橡胶-来解决这个问题，该材料以其对水分和氧气的不渗透性而闻名。我们将证明丁基橡胶的不渗透性和柔软的机械性能可以生产可拉伸的有机发光器件和有机太阳能电池，实现在环境条件下的长期运行。

Electronic devices of the future will be built on soft, polymeric materials, making them stretchable, twistable, and deformable. This stretchability enables applications impossible to achieve with current rigid materials, such as flexible lighting, displays, and solar cells; soft, pressure-sensitive skins for robotics; and conformable biomedical sensors that can be laminated on skin or implanted into the human body to detect and display information. Research in stretchable electronics, however, has exclusively used stretchable silicone rubber materials that are highly permeable to oxygen and moisture, which severely degrade the organic electronic materials in the devices and drastically shorten device lifetime. Our research aims to solve this problem by implementing a different stretchable material - butyl rubber - that is notable for its impermeability to moisture and oxygen. We will demonstrate that the impermeability and soft mechanical properties of butyl rubber can produce stretchable organic light-emitting devices and organic solar cells that achieve long-term operation under ambient conditions.
