Low Friction High Efficiency Tribo-electrification Principle of High Density Graphene Layer Edges Embedded Nanosurface

No.51575359

As a new type of green power technique, tribo-electrification has recently attracted enormous attentions. However, the relationship between surface tribology behavior and tribo-electron output during the tribo-electrification process has

not been thoroughly studied so far, which tangled the development of high efficiency tribo-electrification and its practical applications. Our earlier research has found that other than large scale graphene layer(s), carbon nanosurface containing abundant graphene layer edges is capable of large-amount electron storage due to the undercoordination of edge atoms, and can lead to low friction owing to the surface polarization effect at edge quantum-wells. These principles shed light on a new principle of low-friction-high-efficiency tribo-electrification based on graphene layer edges effect. Therefore, this application proposed a scientific problem of “Low friction high efficiency tribo-electrification principles of high density graphene layer edges embedded
nanosurface”, and will carry out researches in four steps, starting with the manufacturing and quantitative characterization of nanosurface with different density of graphene layer edges, focusing on the low friction behavior of the nanosurface as well as its high electric output property which are induced by the polarization effect at edge quantum-wells, and finally aiming at the development of low friction high efficiency tribo-electrification device based on the above fundamentals. The research outcome is beneficial for exploring the application of graphene nano structured carbon films in tribo-energy field, and have major
significances on enriching traditional “energy-saving” tribology, and opening up the emerging “energy-giving” tribology.
