Tailoring of Anisotropicity of Block copolymer Particles by Controlled co-assembly of Block Copolymers and Nanoparticles |
| 초록 |
Precise control of interfacial interactions leads to a dramatic change in shape and morphology of diblock copolymers self-assembled under confined geometry of emulsion droplet. Key to these changes is the addition of Au-based surfactant nanoparticles which are adsorbed at the selective and desired locations. Anisotropic particles of ellipsoid and convex lens-shaped were synthesized by balancing interfacial interaction between two different blocks of copolymers and surrounding media. The mechanism of formation for these novel nanostructures was investigated by systematically varying the size and the volume fraction of SNPs with the results showing the critical nature that the segregation of SNPs to specific interfaces plays in controlling structure. A theoretical description of the system allows the size distribution and aspect ratio of the asymmetric block copolymer colloidal particles to be correlated with the experimental results. |
