Controlling 3D Assembly of Nanoparticles within Block Copolymer Particles |
| 초록 |
Self-assembly of block copolymers (BCPs) with inorganic nanoparticles (NPs) have great potential to develop well-defined nanostructures with fine-tuned functionalities. Entropic effect arose from interfacial interactions between NPs and BCPs is a critical factor in determining the structures of hybrid particles. Here we present the entropy-driven co-assembly of polymer-grafted Au NPs and BCPs in emulsion. The hybrid particles show dramatic structural transitions such as crusted, seeded and alternate layered onions according to different degree of entropic interactions. The formation mechanism of the hybrid particles is discussed using cryogenic electron microscopy analysis as well as theoretical model. |
