PAN静电纺丝膜基摩擦纳米发电机的性能研究OA北大核心CSTPCD

The use of environmental energy can effectively alleviate the negative impact of resource scarcity and battery pollution,where wind energy is one of the most promising energy sources.To effectively utilize the wind power in daily life,a vibrating friction nanogenerator was designed with contact independent layer mode.The effects of wind speed,device gap and flutter film size on frequency and electrical output signal were studied by using electrospinning film of polyacrylonitrile and polyvinylidene fluoride as friction materials.The results show that the PAN electrospinning film can be used as the positive electrode layer,which has excellent mechanical properties and high temperature stability.PVDF electrospinning film has higher wear resistance and polarization degree.The maximum output power of the F-TENG can reach 164.6 μW with short circuit current of 9.69 μA and open circuit voltage of about 112.3 V.The wind-powered F-TENG can light up at least 150 commercial LEDs.After connected with rectifier devices,it can power up low-power electrical appliances such as calculators.Here the application of electrospinning film was extended in friction nanogenerators.
