摘要
通过微纳米转印技术对聚二甲基硅氧烷(polydimethylsiloxane,PDMS)驻极体材料进行表面微结构处理,系统地研究了3种表面结构(定向线状、规则凹块和不规则粗糙)对接触分离式摩擦纳米发电机输出特性的影响。实验结果表明,驻极体材料的表面比表面积越大,越有利于提高摩擦纳米发电机的输出特性。在应用方面,本文利用摩擦纳米发电机收集机械振动产生的电能,实现了电诱导生长ZnO纳米棒阵列,并且与传统电化学三电极系统下生长的ZnO纳米线阵列进行了对比。本文展现了摩擦纳米发电机在自驱动系统中的潜在应用价值.
To find the influence on the output characteristic of contact-separation mode triboelectric nanogenerator,surface micro-structure on PDMS film is obtained by the micro/nano transfer printing technology,and three kinds of surface microstructures （aligned lines,regular concaves and irregular roughness）are systematically studied.Experiment results indicate that specific sur-face of PDMS can greatly improve output properties of triboelectric nanogenerator.In terms of application,the growth of ZnO nanowire arrays in electric induction generated by the triboelectric nanogenerator is carried out,and compared with ZnO nanowire arrays prepared by traditional three electrode electrochemical system.This paper shows the potential application of triboelectric nanogenerator in the self-powered synthesis system.
