在这里，我们展示了一种简单而有效的方法，制造聚合物散射基板的柔性有机发光二极管（OLED），不需要昂贵的图案化，蚀刻，或成型工艺，方面是理想的商业化的大规模照明面板。系统地研究了相对折射率、粒子尺寸和掺杂浓度对透明无色聚酰亚胺（cPI）薄膜透过率和雾度的影响。结果表明，随着粒子与聚合物基体折射率差的减小，薄膜透过率和雾度的降低沿着减小，并可通过增大粒子尺寸或掺杂浓度来补偿。
Here we demonstrate a simple and effective method of fabricating polymeric scattering substrate for flexible organic light-emitting diodes (OLEDs) that require no costly patterning, etching, or molding processes, aspects that are desirable for the commercialization of large-scale lighting panels. Systematic study of the influences of relative index of refraction, particle size, and doping concentration on transmittance and haze of transparent colorless polyimide (cPI) films was carried out. It was found that the reduction of transmittance and haze of the doped films decreases along with the decrease of the difference of refractive index between the particles and polymer matrix, and it could be compensated by the increase of particle size or doping concentration.
