Mechanochemical preparation of polymeric composites consisting of polyamide and clay materials

摘要

The mechanism of mechanochemical formation of composites consisting of PA-6 polyamide and clay minerals (pyrophyllite, kaolinite) was studied by IR spectroscopy and X-ray diffraction analysis. Composites with chemical bonding between the components are formed by activation of polyamide-pyrophyllite mixtures at polymer content c a parts per thousand currency sign 10 and of polyamide-kaolinite mixtures at c a parts per thousand currency sign 5. Increased polymer content of the starting mixture "inhibits" the disordering of the silicate structure in the course of activation. Modification of polymers with mechanochemically formed polyamide/clay mineral composites improves the physicomechanical characteristics of the composite materials obtained.
