Wetting of a sessile droplet on structured or patterned surface can be found in a broad range of applications. The researchers have been promoted to keep working on the topic. The review is on the basis of the recent experimental advances on the sessile droplet wetting on the hydrophobic, hydrophilic, or combined hydrophobic and hydrophilic surfaces under isothermal conditions, and on heating or cooling substrates having nonisothermal conditions. More attention has been paid on the wetting configuration between the sessile droplet and the structured substrate; the research gap has been discussed on identifying the three-phase line shape. Further, the three-dimensional measurement for the sessile droplets on the patterned surfaces with focusing more on the contact line of sessile droplets might reveal new physical insights. This review targets at building a holistic overview on the sessile droplet wetting behaviors on the structured substrate in the past 2 years.

固结液滴在结构化或有图案的表面上的润湿可在广泛的应用中找到。研究人员已晋升为继续从事该主题的工作。该综述基于最近的实验进展，即在等温条件下，在无水，亲水或组合的疏水和亲水表面上，以及在加热或冷却具有非等温条件的基底上的无蒂液滴的润湿性。在无蒂液滴和结构化基底之间的润湿构型上已经引起了更多的关注。讨论了识别三相线形的研究空白。此外，在图案化表面上的无蒂液滴的三维测量（更多地集中在无蒂液滴的接触线上）可能会揭示新的物理见解。
