Abstract
We have observed directional pattern growth in a lipid monolayer near the three-phase contact line of the Langmuir-Blodgett meniscus. This growth results from the receding flow of the meniscus due to the change in fluid surface tension upon monolayer compression. A gradient in surface tension forms near the three phase contact line and relaxes as the meniscus recedes to its equilibrium height. This pattern formation may be caused by either directional solidification of the monolayer or the coupling between fluid flow and surface tension of the meniscus.Keywords
