Polymorphic Meniscus Convergence for Construction of Quasi-Periodic Assemblies and Networks of Colloidal Nanoparticles

Quasi‐periodic colloidal networks are constructed on the basis of polymorphic meniscus convergence (MC) in an air‐cavity‐embedded, nano‐colloidal system. Depending on the flow associated with the air‐cavities, the colloidal particles are self‐organized into nanowires through binary MC, Y‐junctions t...

Description
Summary:Quasi‐periodic colloidal networks are constructed on the basis of polymorphic meniscus convergence (MC) in an air‐cavity‐embedded, nano‐colloidal system. Depending on the flow associated with the air‐cavities, the colloidal particles are self‐organized into nanowires through binary MC, Y‐junctions through ternary MC, and X‐junctions through quaternary MC. The colloidal networks in either square or hexagonal form reflect the flow symmetry according to the air‐cavity deformation.
