Controlling Janus Nanodisc Topology through ABC Triblock Terpolymer/Homopolymer Blending in 3D Confinement
2021
Janus particles have drawn considerable interest as colloidal surfactants, microswimmers, and building blocks for colloidal lattices. So far, research primarily focused on spherical Janus particles for which a number of fabrication methods are well established. Janus particles with geometric anisotropy offer shape-dependent properties in addition to surface anisotropy, but their synthesis is more challenging. Here, we report a variety of polymeric Janus nanoparticles synthesized from ABC triblock terpolymer microphases in microemulsion droplets. Evaporation-induced assembly of the ABC triblock terpolymers led to prolate microparticles with A/C lamellae stacked along the particle’s major axi…
Modelling Monomer/Disc Composites Phase Behaviour
2012
Summary: A model developed by Balazs' group to explain the phase behaviour of polymer/clay composites is extended to obtain an expression for the free energy of polymer/thin disc mixtures. Phase diagrams for monomer/disc mixtures are built by minimizing the free energy and calculating the chemical potentials of the three system components. Via the comparison of the diagrams, it is studied the effects of nanodisc size and interaction parameters on mixture stability and attained morphology. The performed predictions between monomers and discs give criteria that advance the properties of the mixture. Changes in monomer concentration and interaction parameters provide a means to prevent van der…
