Abstract
The evolution of fractal nanoparticles of medium size and concentration, which are formed and dynamically change during hydrolytic polycondensation, has been investigated using IR spectroscopy. It is shown that the application of the Smoluchowski rapid coagulation model combined with analysis of the characteristic absorption line intensity in the IR spectra provides a satisfactory estimate of evolution processes occurring in sols of orthosilisic acid. The obtained spectroscopic dependences are compared qualitatively with atomic force microscopy data.
