Acetylated nanofibrillated cellulose (ANFC)/acrylic resin ABPE-10 composite film was prepared by impregnating ABPE-10 into ANFC films under negative pressure, which can enhance properties of ANFC films by forming an interpenetrating polymer network structure between ABPE-10 and the ANFC film. The ANFC/ABPE-10 composite film met the high performance flexible organic light-emitting diode substrate requirement, even when the ANFC dosage was as high as approximately 70%. The transparency of films with different ANFC dosages significantly increased from 67% (42 µm) to 88% (45 µm), as determined by ultraviolet-visible analysis. The composite film inherited the properties of AFNC, with a low coefficient of thermal expansion and a ductile compact structure. The contact angles of ANFC films increased from 49.2° to 102.9° after dipping in ABPE-10. Additionally, the composite films had good surface smoothness and mechanical properties.
通过在负压下将ABPE-10浸渍到乙酰化纳米纤维素（ANFC）薄膜中制备了ANFC/丙烯酸树脂ABPE-10复合薄膜，该复合薄膜可通过在ABPE-10与ANFC薄膜之间形成互穿聚合物网络结构来增强ANFC薄膜的性能。即使ANFC用量高达约70%，ANFC/ABPE-10复合薄膜仍满足高性能柔性有机发光二极管基板的要求。通过紫外可见分析测定，不同ANFC用量薄膜的透明度从67%（42 µm）显著提高到88%（45 µm）。复合薄膜继承了AFNC的性能，具有低热膨胀系数和韧性致密结构。ANFC薄膜在浸入ABPE-10后，接触角从49.2°增加到102.9°。此外，复合薄膜具有良好的表面光滑度和机械性能。
