Abstract

The use of crystals made from silica nanoparticles can be used as a stationary phase for chemical separations. Silica colloidal crystals are loosely held together, and unless treated properly with high temperature sintering they will disperse when exposed to aqueous solutions. The goal of this work is to form these crystals and increase their strength without the use of high temperatures. The silica nanoparticles were deposited via vertical evaporative deposition from an ethanol solution. One of the problems encountered was the formation of a well-ordered crystal. The issues included horizontal drying lines as well as vertical cracks in the crystals. To mitigate these problems, a miniature deposition table was fabricated from aluminum. Following the formation of the colloidal crystals, various treatments were applied to achieve higher strength.
