Guo, Yong; van Ravensteijn, Bas G. P.; Kegel, Willem K. published the artcile< Dimple Colloids with Tunable Cavity Size and Surface Functionalities>, COA of Formula: C9H9Cl, the main research area is dimple colloid tunable cavity size surface functionality.
Dimple colloids with well-defined cavities were synthesized by a modified dispersion polymerization The key step in the procedure is the delayed addition of crosslinkers into the reaction mixture By systematically studying the effect of the delayed addition time and the concentration of the crosslinker on the resulting particle morphol., we identified the dominating driving force that underlies dimple formation. The delayed addition of crosslinkers results in colloids with a core-shell morphol. consisting of a core rich in linear polymers and a crosslinked shell. This morphol. was confirmed by selectively etching non-crosslinked material using DMF. With polymerization proceeding, consumption of monomers present in the swollen particles leads to contraction of the particles, which is larger for the core composed of linear polymers compared to the stiffer crosslinked shell. To accommodate this decrease in volume, the outer crosslinked shell has to buckle, resulting in a well-defined dimple. Furthermore, we extended the procedure to incorporate functional monomers, yielding chem. modifiable dimple particles. Subsequently, we showed that by leveraging the core-shell structure, these dimple particles can be used to prepare dumbbell-shaped colloids with one hollow and one solid lobe. These partially hollow anisotropic particles assemble into strings with well-defined orientations in an a.c. elec. field.
