The formation of patterns after the evaporation of colloidal droplets deposited on a solid surface is an everyday natural phenomenon. During the past two decades, this topic has gained broader audience due to its numerous applications in biomedicine, nanotechnology, printing, coating, etc. This paper presents a detailed review of the experimental studies related to the formation of various deposition patterns from dried droplets of complex fluids (i.e., nanofluids, polymers). First, this review presents the fundamentals of sessile droplet evaporation including evaporation modes and internal flow fields. Then, the most observed dried patterns are presented and the mechanisms behind them are discussed. The review ends with the categorisation and exhaustive investigation of a wide range of factors affecting pattern formation.
胶体液滴在固体表面上蒸发后形成图案是一种常见的自然现象。在过去的二十年中，由于其在生物医学、纳米技术、印刷、涂层等领域的广泛应用，这个话题引起了更广泛的关注。本文详细回顾了与复杂流体（即纳米流体、聚合物）干燥液滴形成各种沉积图案相关的实验研究。首先，本文介绍了包括蒸发模式和内部流场在内的固着液滴蒸发的基本原理。然后，呈现了最常见的干燥图案，并讨论了它们背后的机制。最后，对影响图案形成的各种因素进行了分类和详尽的研究。
