Hollow nano-particle, hollow silica nano-particle, and production method for same |
| abstract |
A hollow nano-particle includes a shell layer containing a block copolymer having a hydrophobic organic chain and a polyamine chain, and silica. A hollow silica nano-particle has a porosity of 20% by volume or more and 70% by volume or less, and a thickness of a shell layer containing silica of 3 nm or more and 100 nm or less. A production method for the hollow nano-particle includes: a step of dropping an aqueous solvent while stirring an organic solvent in which a block copolymer having a hydrophobic organic chain and a polyamine chain is dissolved, to obtain a dispersion liquid of vesicles containing the block copolymer; and a step of adding a silica source to the dispersion liquid of vesicles, carrying out a sol-gel reaction of the silica source using the vesicle as a template, and precipitating silica to obtain the hollow nano-particle. |
