| titleOfInvention | Method for manufacturing hierarchical particles and hierarchical particles |
| abstract | PROBLEM TO BE SOLVED: To provide hierarchical structure particles having external stimulus responsiveness in which solid layers and gel layers are alternately laminated. SOLUTION: A gel-like core layer containing a polymer having no charged group and a copolymer gel of a comonomer having a charged group and a monomer having no charged group provided on the outside thereof are included on the inner peripheral side. A core-shell gel particle composed of one or more shell layers in which charged groups are unevenly distributed is used as a seed particle, and a polymer in which hydrophobic monomers having different components are emulsified and polymerized with respect to the seed particle is layered with a charged gel as an intermediate layer. Is formed in. At least one of the non-charged monomer and the charged comonomer has external stimulus responsiveness. The polymer having no charged group may be an LCST polymer, and the comonomer having the charged group may be a vinyl monomer. [Selection diagram] Fig. 1 |
