제목 Asymmetric hybrid colloidal particles by controlled seeded growth
초록 The creation of a new material often starts from the design of its constituent building blocks at a smaller scale. From macromolecules to colloidal architectures, to granular systems, the interactions between basic units of matter can dictate the macroscopic behaviour of the resulting engineered material and even regulate its genesis. Information can be imparted to the building units by altering their physical and chemical properties. In particular, the shape of building blocks has a fundamental role at the colloidal scale, as it can govern the self-organization of particles into hierarchical structures and ultimately into the desired material. In this presentaton, a simple and general approach to generate an entire zoo of new anisotropic colloids will be discussed, which is based on a controlled deformation of multiphase colloidal particles that can be selectively liquified, polymerized, dissolved and functionalized in bulk. Furthermore, controled functionalization and coating of particles will be demonstrated for patchy and Janus particles.
