Dynamic structural evolution of soft colloidal monolayers under uniaxial compression
Abstract
We use small-angle light scattering to monitor microgel assembly at air/water interfaces during Langmuir trough compression in real time. We observe a reversible 30° reorientation of the hexagonal lattice, mediated by a metastable rectangular phase. This behavior arises from the unique deformability of soft colloids under uniaxial confinement.
