(305f) Phase Behavior and Morphological Features of Self-Assembled Magnetic Handshake Panels

A new platform has been created in which a variety of patterns of magnetic dipoles are encoded into panels, in order to create so-called "handshake materials" with addressable interactions and programmable, self-assembled structures [1]. The different panels’ unique and specific interactions result in different morphologies and properties of their self-assembled structures, with varying degrees of condensation into chains and chain–chain stacking. Using tools borrowed from the fields of polymer physics and crystallography, we quantify these differences in structural morphologies across a large parameter space, and we connect their origins back to the properties of individual panels.
