(19e) Automated Langmuir-Blodgett Deposition of Particles on a Non-Flat Surface
AIChE Annual Meeting
Sunday, November 7, 2021 - 4:15pm to 4:30pm
In this work, we demonstrate the deposition of sub-micron, monolayer particle coatings onto a lenticular substrate, with a repeating ~250 µm negative parabolic topography, through the use of a roll-to-roll automated Langmuir-Blodgett process. The influence of topographic gradient and substrate orientation relative to the drying front are explored through analysis of particle spacing. Additionally, the characterization of coatings as submonolayer or monolayer is also shown to be relative to the local substrate gradient. Understanding of this process opens up automated deposition to a wider range of materials and applications.
