Electrochemical investigation on the polycondensation kinetics of silicon alkoxides by functionalization of the silica network by redox species
The sol-gel polycondensation of tetrametboxysilane has been followed for the first time by functionalization of the oligomeric silane species with a redox active ferrocene. Recording the decrease of the average diffusion coefficient of the mobile species brings information on the sol or gel state, as well as an easy insight of the polycondensation kinetics.
