A particle mold synthesis of 2D Janus nanomaterials is proposed by crosslinking of copolymer self‐assembled monolayers confined within the mold domains. Onto the silica (SiO2) particle surface, mold domains with functional groups such as imidazole are generated. The model copolymer of polyacrylic acid‐block‐polystyrene (PAA‐b‐PS) can be preferentially absorbed onto the domains via electrostatic interactions,...
Janus polymeric cages are fabricated by Pickering emulsion interfacial polymerization. The modified silica particles are used to stabilize the emulsions. Oil-soluble monomers and water-soluble monomers copolymerized in between the voids among the silica particles at the interface, forming amphiphilic Janus polymer shell in which the silica particles are embedded. After removal of the silica particles...
Janus composite nanorings are fabricated by skiving the corresponding arrayed nanotubes. Polymer nanotubes and their arrays are polymerized from the pore surface via ATRP inside porous anodic aluminium oxide membrane (AAO) templates. By a selective partial modification of the interior surface of the polymer nanotubes followed by a favorable growth of other materials, double-shelled composite nanotubes...
