Assemble-and-stretch method for creating two- and three-dimensional structures of anisotropic particles. Academic Article uri icon


  • We fabricate two-dimensional ordered arrays of anisotropic particles by embedding hexagonally close-packed monolayers of spherical latex particles in polymer films and subjecting them to an extensional strain. Furthermore, by stacking several films, we create three-dimensional structures. An important advantage of this approach is the ability to independently control the particle orientation in each layer of the structure. Additionally, the symmetry of a layer is controlled by the orientation of the original array of spherical particles versus the stretch direction. This technique may be readily used to generate structures for photonic applications, as well as to aid fundamental studies of packing of anisotropic particles.
