了表征和测试。结果表明：与纯环氧树脂相比，复合膜的热膨胀系数由 4.6×10 K 下降至 1.9×10 K ，透光
率可达 89%，表面平滑（粗糙度 2.15 nm），机械性能良好。在该基础上，在复合基底上制备聚(3,4-乙撑二氧噻
吩):聚苯乙烯磺酸盐导电电极，将制得的电极分别在 70 ℃和15 ℃环境下放置 3 h，然后对其进行了表面形貌、
电导率等测试，结果表明，温度变化时电极材料与基底结合良好无开裂，电导率稳定（829~872 S/cm）。

Abstract: In order to solve the problem of high expansion coefficient and poor thermal stability of the
flexible organic solar cell substrates, cellulose nanofibrils reinforced epoxy resin composite as a flexible
substrate of organic solar cell was prepared. The thermal, optical and mechanical properties of the
composite were characterized and tested. The results showed the thermal expansion coefficient of the

composite film was 1.9×10 K , lower than that of pure epoxy resin (4.6×10 K ). The composite film had
outstanding light transmittance (89%), smooth surface (roughness 2.15 nm), and good mechanical
properties.Subsequently, poly(3,4-ethylenedioxythiophene): polystyrene sulfonate conductive electrode was
deposited on the composite substrate.The prepared electrodes were placed at 70 ℃ and 15 ℃ for 3 h,
respectively, and then tested for surface morphology, electrical conductivity, etc.The results proved that the
electrode material was well combined with the substrate without cracking when the temperature changed,
and the conductivity remained stable (829~872 S/cm).
