Gravimetric Analysis of Drying Sol-Gel Derived Coatings and Comparison to Theory

摘要: The sol-to-gel transformation in coatings is controlled by concurrent solvent evaporation, diffusion, and polymerization reaction processes. These phenomena are incorporated into a theoretical model based on solving one-dimensional convection-reactiondiffusion equations of mass transfer (Cairncross et al., 1992). provides predictions the drying gelation behavior silica prepared from alkoxide solutions. In this paper, experimental results compared with to gain insight coatings.
