1、超疏水论文：固—液—气扩散法制备超疏水表面【中文摘要】在自然界中,许多生物表面显示出特殊表面浸润性能。所谓的超疏水表面是指水接触角大于150°的表面。目前,已经报道了许多制备超疏水表面的方法,并展望了超疏水表面在自清洁、减反射增透膜、微流体等领域的潜在应用。但是,超疏水表面现有制备方法一般都工艺复杂和费用昂贵,限制了其实际应用。对此,发展简单方便的超疏水表面制备技术仍然是一项具有挑战性的研究课题。本文研究内容如下：1.综述了对自然界中超疏水现象的研究进展,以及在此基础上所发展的仿生超疏水表面的制备方法研究进展,并对超疏水表面的性质和一些潜在应用做出了归纳。2.本文以常见的
2、普通玻璃为基底,探索了一种简单的一步制备超疏水涂层的固-液-气扩散方法。同时采用CA、TG-DSC、FT-IR、FE-SEM对制备的超疏水涂层进行表征,结果表明,制备的超疏水涂层是由无序排列的甲基硅氧烷聚合物纳米纤维构成,静态接触角测试大于160°。3.本文采用二次生长法制备了Silicalite-1沸石膜,重点研究了合成过程中各种合成参数对Silicalite-1沸石膜晶貌和性能的影响。并运用XRD,TG-DSC和FE-SEM对其进行了表征,结果表明,合成的纯硅沸石膜连续、致密的,性能优异。4.在所制备的Silicalite-1沸石膜表面进行疏水化处理,其静态水接触角可
3、以达到160°,疏水性能优异。同时对超疏水涂层耐酸碱性和热稳定性进行了初步的研究。结果表明,制备的超疏水涂层具有很好的耐酸碱性和热稳定性。【英文摘要】Innature,manycreaturesexhibitfascinatingsurfacewettability.Asurfacewhosewatercontactangleisgreaterthan150°iscommonlycalledasuperhydrophobicsurface.Infact,variousmethodsfortheprocessingofsuchsurfacesarebeinginvestig
