Abstract
In this article,to investigate the durability and the reason why it loses the superhydrophobility,the superhydrophobic surfaces on the aluminum modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane(PTES)were prepared,and a series of experiments were designed to verify if the surfaces still maintained the superhydrophobic property after they were treated in the seawater and natural surroundings for a long time.In the experiments,the superhydrophobic surfaces were immersed in the seawater with different water pressures to simulate different depths of seawater for the first time.Moreover,the reasons for the loss of superhydrophobility were analyzed by the scanning electron microscope(SEM)and the X-ray photoelectron spectroscopy(XPS).The results showed that superhydrophobic surfaces had good stability and durability in the natural surroundings,but not that good in the seawater,especially under the water pressures.The decrease of the superhydrophobility was mainly due to the destruction of the micro/nano structure,not the destruction of the PTES coatings.关键词
