“…In another study by regarding the redistribution in terms of migration of starch-based bio-latex particles during coating drying, it was found that the binder migrates differently from the pigment and moves towards the surface of the coating layer. The topmost layer of the binder was found to be beneficial for producing bioactive papers by retaining enzymes at the surface [30,31].…”

A distinctive field in the coatings industry is coating of porous media, which has broad applications including paper, textiles, electronics, filtration, and energy sectors. Fluid penetration is an important issue during direct coating of a liquid bead on porous media, which is driven by the pressure from an external flow field and the surface tension in the porous media. Generally, during the coating process, some level of penetration is desirable to obtain specific material properties, but inadequate or excessive penetration is detrimental. To help control the level of penetration, understanding relationships between operating parameters and penetration are highly desirable. In this article, the current state of academic research on modeling penetration in porous media during common coating processes, especially the slot die coating process, is reviewed. Specifically, the challenges, basic ideas, advantages, and disadvantages of macroscale, microscale, and pore-network models on penetration in porous media are discussed. This article concludes with some recommendations for future work.

“…A major concern when coating porous media is fluid penetration into the substrate. Although some level of penetration is desirable to obtain specific material properties, inadequate or excessive fluid penetration can negatively affect the strength, appearance, functionality, and performance of the resulting material. It has been shown that excessive penetration of Nafion® into the catalyzed gas‐diffusion layer during direct coating can reduce the performance of the fuel cell due to poor gas transport and an imbalance between ionic conductivity and electronic conductivity …”

Analytical models for predicting penetration depth during slot die coating onto porous media

et al. 2014

A series of analytical models have been developed to predict the penetration depth during slot die coating on porous media. Analytical models for both Newtonian and non-Newtonian fluids were derived based on Lubrication Theory, Darcy's law, and a modified Blake-Kozeny equation. Using these models, the penetration depth can be quickly solved and the effects of material properties and processing conditions on penetration depth can be easily investigated. Experiments of coating Newtonian glycerin and non-Newtonian blackstrap molasses onto Toray series carbon paper were conducted to validate developed models. The overall relative error between the predicted and measured penetration depth was found to be typically lower than 20%, which demonstrates the relative accuracy of developed models. Furthermore, based on a parametric study, it was found that the effect of capillary pressure on penetration depth is less than 10% when the ratio of coating bead pressure and capillary pressure is larger than 10.
