Shape Engineering of Nanostructured Cone-Shaped Particles by Tuning Blend Structure of AB Diblock Copolymer and C-Type Copolymer within Emulsion |
| 초록 |
Block copolymers (BCPs) in colloidal confinements can provide an effective route to produce non-spherical particles. Herein, we exploit the blend of poly(styrene-block-1,4-butadiene) (PS-b-PB) BCP and poly(methylmethacrylate-statistical-(4-acryloylbenzophenone)) (P(MMA-stat-4ABP)) sCP within the emulsion to develop a series of particles with different symmetry. The particle shape can be tuned sequentially from striped ellipsoid to Janus-sphere, to cone-shaped by increasing the mole fraction of 4ABP in sCPs (ɸ4ABP). These particles were produced by membrane emulsification method to have monodisperse particle size and shape. Therefore, the shape-anisotropy of monodispersed cone-shaped particles can be precisely tuned, which is supported by quantitative calculation based on the modified theoretical model. The importance of the shape control of the monodispersed cone-shaped particles was demonstrated by investigating the colloidal coating property of these particles. |
