【摘要】 以纤维素纸为基底或电正性摩擦材料的摩擦纳米发电机在柔性电子器件具有潜在应用前景，然而纤维素纸基摩擦纳米发电机需要在高工作频率下才能获得良好的输出性能，限制了纤维素纸基摩擦纳米发电机的应用与发展。为提高纤维素的电正性摩擦性能，将银纳米颗粒原位负载于纤维素纤维表面，制备纳米银复合纸（Ag@paper），并以Ag@paper与聚四氟乙烯薄膜（PTFE）为摩擦材料构建纸基摩擦纳米发电机（P-TENG）。结果表明：P-TENG开路电压可达95 V，短路电流可达0.19μA。该P-TENG在长期工作过程中还能防止细菌生长，因而可用于开发新型可穿戴电子产品。更多还原

【Abstract】 Cellulose paper can be used as the substrate and tribopositive materials in triboelectric nanogenerators, which have potential applications in flexible electronic devices. However, to obtain high output performance, cellulose paper-based triboelectric nanogenerators(P-TENG) needed to be operated at high frequency, limiting the application and development of them. Herein, the silver nanoparticles modified cellulose paper(Ag@paper) was prepared by using an in-situ synthesis method for enhancing the tribopositive performances of cellulose paper, and the P-TENG with open-circuit voltage of 95 V and short-circuit current of 0.19 μA was fabricated by Ag@paper and teflon film(PTFE). The P-TENG can also prevent the accumulation of bacteria during long-term operation, thus it had application prospect on wearable electronics.更多还原
