Ammonium Hydroxide as a Catalyst for Vapor Phase Deposition of Silanes ID: 2012-054

This technology introduces an environmentally friendly, cost-effective, and reliable method for silane deposition using ammonium hydroxide as a catalyst.

Technology Overview

The study conducted by Dr. Matthew R. Linford and Vipul Gupta at Brigham Young University focuses on the use of ammonium hydroxide for catalyzing the vapor phase deposition of silanes. This process is aimed at improving the efficiency of silane deposition by facilitating the removal of hydrogen from silanol groups, thereby enhancing siloxane bond formation. The research includes experimental data that demonstrates the impact of varying concentrations of ammonium hydroxide on the deposition process, evidenced by changes in contact angles and surface roughness.
