Capillary sorting of particles by dip coating
WebThe dip-coating dynamics, including the film thickness and composition, are recorded with a digital camera (Nikon D7100) and a 200-mm macrolens focused above the meniscus. … Webafter coating. Thus, dip coating, in particular combined with evaporation, has been considered for optical applications, self-assembling of particles and wettability treatments (Ghosh, Fan & Stebe 2007;Mechiakhet al. 2010; Berteloot et al. 2013;Mahadiket al. 2013). More recently, several studies have considered the dip coating of monodisperse

WebJun 6, 1990 · 2.2. Dip coating In dip coating, the substrate is normally withdrawn vertically from the liquid bath at a speed Uo (Fig. l(a)). The moving substrate entrains the liquid in a fluid mechanical boundary layer that splits in two above the liquid bath surface, the outer layer returning to the bath 4 (see Fig. l(b)). WebDecember 2024: Our work on dip coating of suspensions has been accepted for publication in Soft Matter. In this paper, we report the existence of three regimes of dip coating in non-Brownian suspensions: pure liquid, heterogeneous coating and homogeneous suspension films. We provide the domain of existence of these different regimes.

WebWe also provide an estimate of the range of capillary number to separate particles of given sizes. The combination of this technique with the scalability and robustness of dip coating makes it a promising candidate for high-throughput separation or purification of industrial and biomedical suspensions. WebWhen dip coating is used for a continuous-sheet substrate, the coating process can run indefinitely so long as the reservoir is replenished [31,32]. This combina- tion of …
