摘要：
This study investigates the triboelectric performance of nanogenerators based on copy paper (CP) and barium titanate (BTO) with varying concentrations (0%, 5%, 10%, 15%, and 20%). BTO was coated onto the paper surface via screen-printing, significantly enhancing the triboelectric properties. Results showed that as the BTO concentration increased, the output performance improved, with optimal performance observed at 15% BTO. At this concentration, the nanogenerator produced an output of 103 V and 3.6 mu A. The CP/BTO nanogenerator demonstrated stable performance over 57,600 cycles at 4 Hz frequency and 40 N applied force, indicating excellent durability. The device attained a maximum power density of 32.4 mu Wcm2, highlighting the efficiency improvement through BTO integration. Various parameters including BTO concentration, applied force, and frequency were studied to optimize device performance. The CP/BTO device successfully powered 60 LEDs and a calculator, demonstrating its potential for practical energy harvesting applications. This research presents a promising approach for developing low-cost, environmentally friendly power-generating systems for wearable and portable devices.
