基于激光诱导石墨烯电极的柔性纸基摩擦纳米发电机
Flexible paper-based triboelectric nanogenerators based on laser-induced graphene electrodes
摘要
Abstract
To relieve the pressure caused by the scarcity of traditional energy sources and simultaneously reduce the envi-ronmental harm during the energy development and consumption processes,laser direct-writing technology was adopted.Kraft cardboard was transiently ablated to prepare flexible laser-induced graphene(LIG)electrodes in one step.Then,Ecoflex silicone rubber was spin-coated on the LIG flexible electrodes to form a negative tribo-electric layer,thus preparing a single-electrode flexible paper-based triboelectric nanogenerator(CP-TENG).The influence laws of laser scanning parameters such as scanning rate and laser power,as well as the thickness of the negative triboelectric layer,on the triboelectric nanogeneration performance were analyzed,and the optimal process parameters were determined.To further enhance the output performance,an origami-structure design was used to prepare a multi-unit structured paper-based triboelectric nanogenerator.The results showed that when the laser scanning rate was 15 cm/s,the scanning power was 3.6 W,and the thickness of the negative tri-boelectric layer was 0.9 mm,the prepared single-electrode CP-TENG achieved high-performance output.Under the conditions of a load frequency of 10 Hz and a load force of 10 N,the peak-to-peak open-circuit voltage of CP-TENG could reach 61.8 V.When the load force was increased to 16 N,the peak-to-peak open-circuit volt-age could reach up to 97.1 V.When the load resistance was 18 MΩ,the output power was 47.8 μW.The single-electrode CP-TENG could withstand various bending and folding deformations with stable performance.After 1 000 folds,the sheet resistance of LIG only slightly increased from the initial 16 Ω/sq to 18 Ω/sq,still main taining good output performance.The output performance of the multi-unit structured CP-TENG was further improved.When the number of friction units increased from 1 to 6,the peak-to—peak open-circuit voltage increased from 41 V to 188 V.Compared with the braided structure,the multi-unit CP-TENG with a meshing structure had better output performance,and its open-circuit voltage could reach 389 V.By attaching the paper-based triboelectric nanogenerator to human joint parts,self-powered monitoring of human joint postures could be achieved.关键词
