摘要	The evaporation of colloidal droplets on solid surfaces frequently results in the undesirable "coffee ring effect", a well-known phenomenon that has attracted significant attention across various fields, including inkjet printing, micro/nano fabrication, and coatings, due to its adverse implications. Although several control strategies, such as heating, exist to mitigate the coffee ring effect, to develop a simple, efficient, and non-contact universal approach still remains a significant challenge. In this study, we present an innovative approach to enhance the interfacial evaporation of droplets by implementing actively controlled airflow. This airflow generates intense internal motion within the droplet, promoting a more uniform dispersion of colloidal particles. Simultaneously, it significantly increases the evaporation rate at the liquid-air interface, facilitating the capture of colloidal particles and their arrangement into well-organized crystal structures. In contrast to conventional methods, this approach does not necessitate any alterations to the substrate or liquid, thereby demonstrating broader applicability. We are optimistic that this advancement will positively influence the fabrication of high-quality, highperformance printed electronics.
