The major components of oxygen scavenger films are polymer, oxidizable compounds, and catalyst. In this study, the oxygen scavenging capacity and oxygen scavenging rate of the oxygen scavenger film in water were determined for evaluating the performance of the films. The results showed that the film composed of polyethylene, 4% sodium erythorbate, and 0.1% EDTA cupric salt had the best oxygen scavenging efficiency. On the 1st and 10th day, the oxygen removed rate of the film was 0.02 and 0.065 mg/cm2/day, respectively, from 300 ml water.

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.
相对于硬脂酸修饰表面,氟硅烷修饰表面对水滴具有更低的接触角滞后和较低的黏着,这可能是因为氟硅烷比硬脂酸具有更低的表面自由能所致。2、利用酸辅助的表面氧化技术制备了由Cu8(PO3OH)2(PO4)4·7H2O单晶组成的三维蜂巢状多孔结构,孔尺寸约为几百纳米到2微米,二维的纳米片厚度为50~100 nm。
