Mechanical activation of the inorganic polymer fl int and its mixtures with sevilen and polyamide polymers and SiO2 nanoparticles was studied using IR spectroscopy and x-ray phase analysis. It was found that active acidic centers appeared on the fl int surface during mechanical activation. Adsorbed water did not form H-bonds to them. Sevilen reacted with fl int during mechanical activation. SiO2 nanoparticles did not affect mechanical activation of flint. Polyamide did not react mechanochemically with flint, in contrast with sevilen.
