Description
技术领域
本发明涉及双目视觉三维测量技术领域，具体为一种超疏水仿生纳米复合涂层的制备方法。
背景技术
仿生超疏水表面因具有良好的自清洁、流体减阻、防腐蚀、防冰以及防污损性能，在工业上展示出了较强的应用潜力，引起了人们的广泛研究。超疏水表面的润湿性由以下两个因素共同决定：较低的表面能，以及表面的粗糙结构，研究表明在目前已知极低表面能物质的光滑固体表面，液滴的接触角最高仅达到120°，远达不到超疏水性的要求。然而引入微观结构可显著地提高固体表面非润湿性能，表观接触角可达150°甚至更高。因此制备超疏水表面的关键是在固体表面构筑合适尺寸的微观结构，目前随着技术的不断发展，出现了许多种在固体表面构建微观结构的方法，例如细微加工技术、等离子体刻蚀技术、化学或者物理气相沉积技术、化学刻蚀技术、溶胶凝胶技术、静电纺丝技术及喷涂技术等。
现有的超疏水仿生纳米复合涂层在使用时，介质冷却效率较低，导致纳米微粒在形成时效率较低，同时混合液在搅拌时容易产生大量的泡沫，使其容易影响超疏水仿生纳米复合涂层制备质量。

S2：将形成的纳米微粒与超疏水剂进行混合搅拌，混合完毕的纳米微粒与超疏水进行排放，利用除沫器可将搅拌产生的泡沫进行去除；
S3：对排放的纳米微粒与超疏水混合液进行筛分，将烷基硅氧烷加入筛分好的混合液中搅拌反应；
S4：反应后的混合液可通过浸泡的方式对混合液进行浸泡，将浸泡后的混合液涂抹基材的表面进行加热；
S5：对涂抹混合液的基材进行烘干，造成超疏水仿生纳米复合涂层的制备。
优选的，所述S3中混合液搅拌下55℃反应3-7h，获得构建微纳低表面能粗糙层的悬浮液。
优选的，所述S4中基材75℃加热一小时。
优选的，所述S1中吹风机位于半导体的前方，使其加快介质冷却效率。
