查询词典 two dimensional

Three dimensional (3D) honeycomb-like porous structures made up of nanoslices of hydroxy cupric phosphate heptahydrate Cu8(PO3OH2(PO4)4·7H2O single crystals were constructed by a facile assistant surface oxidation technology. The pore size of the 3D structure ranges from hundreds of nanometers to two micrometers, and the thickness of the two dimensional (2D) nanoslices is about 50~100 nm. The wettability of the porous surfaces was transformed from superhydrophilic to superhydrophobic by chemical modification with octadecanethiol or PDES.
