Abstract
A method of manufacturing a charged particle, comprising: a) providing a mother particle; and b) forming a coating layer that covers at least a part of a surface of the mother particle, wherein the step b) includes: coupling a first chemical compound having at least a part where is going to be a starting point of living polymerization to the surface of the mother particle; and polymerizing a second chemical compound having an ionic group or a functional group convertible to an ionic group so as to form a polymer through the living polymerization that starts from the starting point of the first chemical compound.
Claims10
A charged particle, comprising:
- a mother particle;
- and
- a coating layer covering at least a part of the mother particle,
- the coating layer including a polymer, and
- the polymer including a first chemical compound that couples to a surface of the mother particle and a second chemical compound that reacts through a living polymerization that starts from a starting point of the first chemical compound,
- wherein the polymer has cationic groups at its side chains, which are ramified from its main chain.
