“…Numerous experimental studies, as effectively summarized by Schulz and Keddie in a review of 2018 [31], highlighted that the surface region is responsible for defining fundamental properties, such as wetting, hardness, and electrical conductivity. For example, Nunes et al [54] detected greater mechanical resistance in auto-stratified colloidal coatings by enriching the surface in hard particles. In our binary system, WPI colloids can be approximated to hard spherical colloids.…”

“…Our data will allow other researchers to engineer stratified coatings in a quantitative way, such as in the manufacture of scratch-resistant coatings from binary blends of hard and soft particles. 52 Additionally, the results highlight the effects of stratification in disrupting the formation of binary colloidal crystals at film surfaces in a horizontal drying process, which has relevance to optical properties. 43,44…”

In concentrated suspensions, stratification occurs in experiments only for the higher size ratio α = 7. Simulations using a high Péclet number, additionally find stratification with α = 2, when ϕ is high enough. Our results provide a quantitative understanding of the conditions under which stratified colloidal films assemble. Our research has relevance for the design of coatings with targeted optical and mechanical properties at their surface.

“…Reinforcing particles are also primarily required at the surface of polymer films to improve hardness. Nunes et al showed that the stratification of hard nanolatex particles improved surface hardness as well as anti-blocking and fat resistance 41 .…”
