Engineering the Shape of Block Copolymer Particles by Aspect Ratio-controlled Nanorod Surfactants |
| 초록 |
The effect of aspect ratio (AR) of nanorod surfactants and the domain size of block copolymers (BCPs) on the shape and internal morphology of BCP particles was systemically investigated using CuPt nanorods with different AR values ranging from 1 to 20. Selective positioning of nanorod surfactants on the P4VP(PDP) domain effectively tuned the interfacial interaction between two different PS/P4VP(PDP) domains of the particles and the surrounding water during emulsification and induced a dramatic morphological transition to convex lens-shaped particles. Precise and systematic control of interfacial activity of nanorod surfactants was also demonstrated by varying the concentration, and aspect ratio of NR surfactants. In addition, control over the shape anisotropy of these lens-shaped particles could be realized by adjusting the molecular weight of the block copolymers and concentration of NR surfactants. |
