Description

technical field [0001] The invention relates to the field of new energy development and nano power generation, in particular to a friction nano generator containing an electron receiving layer and a preparation method thereof. Background technique [0002] Energy issues have always been one of the hot issues of human society. With the continuous depletion of available fossil energy, the development of green new energy has become more and more urgent. Since it was first reported in 2012, triboelectric nanogenerators have achieved rapid development due to their advantages such as high conversion efficiency, low manufacturing cost, simple structure, high flexibility, and wide application range. Utilizing the coupling effect of friction electrification and charge induction, the friction generator can convert the mechanical energy of daily life such as people's walking, vibration, rotation, wind blowing, flowing water, etc. into electrical energy. [0003] The power generation ...
