【摘要】:为拓展三维丝网的应用,强化其微结构作用效果;通过采用直接氧化法和液相、气相沉积成功制备超浸润性Cu丝网(200PPI)。利用扫描电镜、透射电镜、X射线衍射、接触角仪及高速摄像分别对丝网的结构、形貌及浸润性进行表征,并获得膜层的最佳制备工艺。结果表明:曲面丝线上的超亲水膜层呈现为单层微米尺度的刀片花结构,液滴在此表面上的铺展速率可达3.5m/s;经液相、气相沉积方法对其氟化处理后,超亲水丝网成功改性为超疏水丝网;并证明试样在96℃氧化液中氧化15min、液相沉积30min、180℃下热处理20min可获得大于150°的超疏水性能。
[Abstract]:In order to expand the application of three-dimensional wire mesh and enhance the effect of its microstructure, the superwetting Cu wire mesh 200PPI was successfully prepared by direct oxidation and liquid phase deposition. The structure, morphology and wettability of the wire mesh were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), contact angle instrument (TGA) and high speed camera, respectively, and the optimum preparation process of the film was obtained. The results show that the superhydrophilic film on the surface of the surface is a single-layer micrometer blade with a spreading rate of 3.5 m / s, and it is fluorinated by liquid phase and vapor deposition. The superhydrophobic wire mesh was successfully modified into superhydrophobic wire mesh, and the superhydrophobic properties of 20min were obtained when the sample was oxidized in oxidation solution at 96 鈩,
