Cellulose is one of the emerging materials as a natural polymer. In this work, cellulose nanofiber is utilized as a dielectric layer in triboelectric nanogenerator. To retain the flexibility of the fabricated paper, Ag nanowires layer is employed for electrode material and counter triboelectric layer simultaneously. This triboelectric nanogenerator is fabricated by a filtration process with different cellulose nanofiber and Ag nanowire condition. This triboelectric nanogenerator operates by contacting and separating of only two same bilayer paper consisting of cellulose nanofiber and Ag nanowire. Cellulose nanofiber and Ag nanowires layer acting as not only triboelectric layer and counter-triboelectric layer but substrate and electrode respectively. The case of cellulose nanofiber solution homogenized with 20 passes in 1000 bar and Ag nanowire with 0.1 wt% solution shows the optimal peak corresponding to 21 V of open-circuit voltage and 2.5 µA of short-circuit current. The maximum power output represents the value of 693 mW/m² for a 10 MΩ external resistance. Fabricated device is dispersed and completely dissolved in deionized water by using sonicator for 30 minutes and returns to original ingredient without producing any pollutant. This nanogenerator plays roles of not only harvesting ambient energy but folding sensor, humidity sensor, and e-paper-like device due to the paper-like characteristics and nano-porous of cellulose nanofiber and Ag nanowires.

纤维素是作为天然聚合物出现的新兴材料之一。在这项工作中，纤维素纳米纤维被用作摩擦电纳米发生器中的介电层。为了保持人造纸的柔韧性，Ag纳米线层同时用于电极材料和反摩擦电层。该摩擦电纳米发电机是通过过滤工艺制造的，具有不同的纤维素纳米纤维和银纳米线条件。该摩擦电纳米发生器通过仅接触和分离由纤维素纳米纤维和Ag纳米线组成的两个相同的双层纸来运行。纤维素纳米纤维和银纳米线层不仅分别充当摩擦电层和反摩擦电层，而且还充当基底和电极。纤维素纳米纤维溶液经过1000次均质20次均质的情况 含有0.1  wt％溶液的bar和Ag纳米线显示出对应于21  V开路电压和2.5  µA短路电流的最佳峰值。对于10MΩ的外部电阻，最大输出功率表示693  mW / m ²的值。使用超声仪将制造的设备分散并完全溶解在去离子水中30 分钟，然后返回原始成分，而不会产生任何污染物。由于纤维素纳米纤维和银纳米线具有纸状特性和纳米孔，因此这种纳米发电机不仅起到收集环境能量的作用，而且还起到折叠传感器，湿度传感器和电子纸状设备的作用。
