This talk introduces a flexible approach for synthesizing uniform anisotropic non-spherical polymer colloids in a bulk process. This work is inspired by recent advances in the synthesis of non-spherical polymer particles by the seeded polymerization method; on heating monomer-swollen crosslinked particles, the elastic stress driven by the entropy change of the swollen networks causes phase separation and eventually results in macroscopic deformation of the particles. This exquisite behavior provides a convenient means to manipulate the geometry and surface properties of non-spherical particles. In this study, we fabricate dumbbell-type particles and characterize their anisotropic properties. We also produce amphiphilic dumbbell particles and assemble them at interfaces to confirm the applicability as colloid surfactants. Furthermore, we fabricate conducting dimer particles and demonstrate their applicability to electrorheology fluids. |
