| Outline of Final Research Achievements |
We demonstrated that one-dimensional colloidal chain composed of Janus particles utilizing hydrogen bonding interaction of steric stabilizers of the Janus particle. The colloidal structure can be controlled by changing the surface area ratio of the Janus particles such as dendritic and grafting colloidal structures. It was clarified that the distribution of the association number was in a good agreement with the theoretical curve calculated from step-growth polymerization theory. We also demonstrated preparation of colloidal structure using non-spherical particles. We unexpectedly discovered a facile and novel approach to prepare monodisperse polystyrene (PS) particles having a “cylindrical” shape. Notably, unique adsorption behavior of the cylindrical particles on an oil droplet was observed, in which the cylindrical particles connected head to head to form a network (colloidal structure) that acted as a cage around the oil droplet.
