Synthesis of Silica Nanoplatelets with Controllable Wettability Using -Sheet Structured Polypeptide Templates |
| 초록 |
Colloidal particles with 2-dimensional geometry exhibit high adhesion energy at the interface so that there have been tries to synthesized new types of particles with a tailored platelet structure. Herein, we introduce an approach to synthesize silica nanoplatelets (SiNPs) with controllable wettability. For this, we synthesized the SiNPs by precipitating silica from polypeptide templates with -sheet structured conformation. The surface modification of SiNPs led to formation of a preferred configuration at the oil-water interface. Taking advantage of high adhesion energy coming from the platelet-geomerty of SiNPs, we could readily obtain stable O/W and W/O type Pickering emulsions. These results highlight that the SiNPs developed in this study could have great potential for applications to complex multiphasic fluid systems. |
