本研究提出了一种使用聚维硅氧烷（PDMS）制造有机发光二极管（oled）的柔性衬底。为了降低OLED制造所需的表面粗糙度和增强表面刚度，我们优化了PDMS前驱体的成分，并引入了一个由Al2O3纳米颗粒组成的强度增强层，并将其嵌入到表面附近。实验结果表明，在该衬底上制备的三羟基喹啉铝（Alq(3)）基oled可以在2.2 V的低阈值电压下成功导通，弯曲半径为3.0 cm。(C) 2009日本应用物理学会。
This study presents a flexible substrate using poly(dimenthylsiloxane) (PDMS) to fabricate organic, light-emitting diodes, (OLEDs). To reduce surface roughness and enhance surface stiffness necessary for OLED fabrication, we optimized the constituents of PDMS precursor and introduced a strength-enhancement layer, which comprises Al2O3 nanoparticles, and embedded it near the surface. Experimental results showed the tris(8-hydroxyquinolinato) aluminum (Alq(3))-based OLEDs fabricated on the substrate can be successfully turned on at a low threshold voltage of 2.2 V with a bending radius of 3.0 cm.
