Binary Nanoparticle Superlattices Assembled via Hydrogen Bonding of Block Copolymer Micelles and Colloidal Silica
We report the assembly of binary nanoparticle superlattices (BNSLs) composed of amphiphilic block copolymers and colloidal silica, driven by a balance between complementary associative and self-repulsive interactions. In aqueous media, spherical polystyrene-block-poly(ethylene glycol) (PS-b-PEG) micelles co-assemble...
