摩擦起电的界面调控与应用研究

Triboelectrification is one of the most common effects in our daily life. When two materials come into frictional contact, they become electrically charged through triboelectric charging. Static electricity generated by triboelectrification, which has proven useful in many areas such as xerography, electrostatic air cleaning and electrostatic painting, on the other hand, can generate electric discharge, which is a hidden danger for petroleum transport and industrial production and may result in heavy casualties and economic losses. It is very important to reveal the mechanism of triboelectric charge generation and realize effective control of triboelectric charge quantity at the interface. Here we summarize the recent progress in the studies of interface control and utilization of triboelectrification. The challenge and prospective investigation trends of interface control and utilization of triboelectrification are also proposed and discussed.
