Anhydrous Supercritical Carbon Dioxide Method for the Controlled Silanization of Inorganic Nanoparticles

摘要

In recent years, much attention has been paid to the surface modification of inorganic nanoparticles with organic functional molecules. The ability to control physical and chemical properties of the surface is crucial for many applications. The engineering of a nanoparticle's surface can be performed either by particle precipitation and in situ coating techniques (e.g., dispersion or microemulssion processes) or by ex situ coating of a produced powder (e.g., Langmuir-Blodgett and self-assembly methods).
