【摘要】：為拓展三維絲網(wǎng)的應(yīng)用,強(qiáng)化其微結(jié)構(gòu)作用效果;通過采用直接氧化法和液相、氣相沉積成功制備超浸潤性Cu絲網(wǎng)(200PPI)。利用掃描電鏡、透射電鏡、X射線衍射、接觸角儀及高速攝像分別對(duì)絲網(wǎng)的結(jié)構(gòu)、形貌及浸潤性進(jìn)行表征,并獲得膜層的最佳制備工藝。結(jié)果表明:曲面絲線上的超親水膜層呈現(xiàn)為單層微米尺度的刀片花結(jié)構(gòu),液滴在此表面上的鋪展速率可達(dá)3.5m/s;經(jīng)液相、氣相沉積方法對(duì)其氟化處理后,超親水絲網(wǎng)成功改性為超疏水絲網(wǎng);并證明試樣在96℃氧化液中氧化15min、液相沉積30min、180℃下熱處理20min可獲得大于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，
