FIELD: chemistry.
SUBSTANCE: method of modifying montmorillonite involves treatment of natural montmorillonite via ultrasonic dispersion, equimolar amounts of ε-caprolactam and polyfluorinated alcohols in ethanol. The dried reaction mass undergoes oligomerisation in nanolayers of montmorillonite ε-caprolactam with polyfluorinated alcohols in a vacuum-sealed ampoule.
EFFECT: invention enables to obtain material with improved tribochemical properties.
