Abstract

In this study, VO_x was prepared by oxalic acid and vanadium pentoxide under nitrogen atmosphere and SiO₂ was grown on the surface of VO_x. Block copolymer (PCL-b-PDMS-b-PCL) was synthesized by hydroxy terminated poly(dimethylsiloxane) and caprolactone, and the composite material containing inorganic particles was obtained by blending VO_x/SiO₂ with PCL-b-PDMS-b-PCL. The porous film was constructed by breathing pattern method, and the supersmooth surface was obtained by injecting lubricating oil into the porous film. The composite was tested by Fourier transform infrared spectroscopy, hydrogen NMR spectroscopy, scanning electron microscopy, contact angle and anti-bacterial adhesion. The results showed that PCL-b-PDMS-b-PCL was successfully synthesized, and the prepared composite material containing inorganic particles had excellent superslippery properties after oil injection, and the sliding angle was 2°.

制备 VOx/SiO2 掺杂共聚物超滑表面复合材料

摘要本研究用草酸和五氧化二钒在氮气环境下制备了VOx，并在VOx表面生长了SiO2。羟基封端聚二甲基硅氧烷和己内酰胺合成嵌段共聚物（PCL-b-PDMS-b-PCL），将 VOx/SiO2 与 PCL-b-PDMS-b-PCL 共混得到含无机颗粒的复合材料。采用呼吸模式法构建多孔膜，并通过向多孔膜中注入润滑油获得超光滑表面。对复合材料进行了傅立叶变换红外光谱、氢核磁共振光谱、扫描电子显微镜、接触角和抗菌粘附性测试。结果表明，PCL-b-PDMS-b-PCL 合成成功，制备的含无机颗粒的复合材料在注油后具有优异的超滑性能，滑动角为 2°。
