Amphiphilic Janus particles are biphasic colloids that have two parts on opposite sides of the particles with different composition or properties. In general, particles with a platelet-geometry exhibit excellent interfacial adhesion energy, which is originated from their high shape anisotropy. Herein, we introduce a new synthetic approach to obtain amphiphilic silica nanoplatelets (ASNPs) which enable self-assembly at an oil-water interface. For this, we first synthesized silica nanoplatelets (SiNPs) from polypeptide-templated silicification and gradually modified them for the preparation of macroinitiator. Firally, the ASNPs were obtained by simultaneously grafting both hydrophilic and hydrophobic polymers on each SiNP surface. It is expected that our ASNPs could find a practical applicability for development of biphasic catalytic reaction-controlled microreactors. |
