在面临能源危机急需可持续发展的当今，开发新能源已成为重中之重。2012年，王中林院士提出的摩擦纳米发电机就具有绿色环保、轻携便捷、成本低廉的方式，在物联网、可穿戴和海洋能收集方面存在一定的优势，成为新能源开发与利用的一个独特手段。本文中，作者使用成本低廉且易于大规模大面积加工的光学干涉方法，制作格子周期灵活可调的摩擦层，并实现接触分离式摩擦纳米发电机，研究格子周期和维度对摩擦纳米发电机输出性能的影响。结果表明，在492.85 nm至1301.1 nm期间，周期越小，输出性能越优越；并且二维结构的输出高出同周期的一维结构70%以上。在此基础上，通过添加压电材料ZnO纳米颗粒以及对比材料TiO_2来研究掺加压电材料对摩擦纳米发电机输出性能的影响。通过开路电压、短路电流以及不同阻值的负载来表征其性能，结果表明相比不掺压电材料其性能提升约90%左右。

It is significant and necessary to develop new energy resources nowadays when we face the energy crisis. In 2012, Dr. Z.L.Wang proposed the concept of triboelectric nanogenerators to solve this problem. As a new energy harvesting way, triboelectric nanogenerators have attracts lots of attentions for their characteristics of easy to take, green and non-pollution. Many nanogenerators were designed in the fields of Internet of Things, Wearable electronics, Marine energy collection and so on. In the thesis, the optical interference method was used to flexibility fabricate the pattern structures of the friction layers. The influence of pattern’s dimension and period intervals on the output performance of the nanogenerators was demonstrated by using the contacting-separation modetriboelectric nanogenerators. The smaller the period intervals is (from 492.85 nm to1301.1 nm), the better the output is. Besides, the output of the nanogenerators with 2D patterns is improved by 70% relative to that of generators with 1D pattern. In addition, the output performance of the triboelectric nanogenerators were further improved by 90% and 41% through adding piezoelectric material ZnO and non-piezoelectric material TiO_2 nanoparticles in the friction layers, relative to that of the cases without nanoparticles, respectively.
