六边形纳米CuI及其超疏水性

Hexagonal CuI powder:superhydrophobic materials without modification by low-free-energy materials

采用一步液相反应法,在常温常压下,制得六边形纳米CuI。无需任何低表面能物质(硫醇或氟烷基)修饰,该样品就表现出超疏水性,接触角达到157°。最为重要的是样品的超疏水性很稳定,在空气中放置半年后,其接触角无明显变化,具有潜在的应用价值。

A facile wet chemical process was developed to fabricate hexagonal CuI powder at normal pressure and temperature.Remarkably,such CuI film displays excellent superhydrophobicity without further modification by low-free-energy materials（thiol or fluoroalkylsilane）,and the contact angle reaches 157°.Importantly,such superhydrophobicity property is quite stable even when it is kept in air for about half a year,which makes it have potential applications.
