摘　　要：Currently,the development of clean and green energy-harvesting solutions is becoming increasingly critical.Batteries have long been considered as the most traditional and efficient technology for powering electronic devices.However,they have a limited lifetime and require constant observation and replacement.To address this issue,triboelectric nanogenerator(TENG)has garnered considerable attention as a prospective sustainable power source for smart devices.Further,several approaches for improving their output performance have been investigated.Herein,we created a unique TENG based on densely packed molybdenum disulfide(MoS_(2))petals grown on electrospun polyacrylonitrile(PAN)fibers(MPF)using a hydrothermal technique.Designed MPF-TENG is used for mechanical energy-harvesting and smart study room touch sensor applica-tions.The effects of pure MoS_(2) powder,PAN fibers,and MoS_(2) grown on the PAN fibers were investigated.MoS_(2) addition enhanced the surface charge,surface roughness,and electrical performance.The MPF-TENG had a maximum triboelectric output voltage,current,charge,and average power density of 245.3 V,5.12µA,60.2 nC,and 1.75 W/m^(2),respectively.The MPF-TENG remained stable for more than 10,000 cycles.The MPF-TENG successfully illuminated blue LEDs,turned on a timer clock,and could be used in smart study rooms to generate energy.This study provides an effective method for improving the performance of TENG by growing MoS_(2) petals on PAN fibers,with promising applications in power supplies for portable electronic devices.Furthermore,the fabricated MPF-TENG was demonstrated to be a potential touch sensor for smart study rooms to save electricity.
