Nanocomposites Based on Polyamide and Montmorillonite Obtained from a Solution

This work deals with the development of method for obtaining polyamide and montmorillonite based nanocomposite, which was modified with polyvinylpyrrolidone by mixing in formic acid solution. The structure and thermophysical properties of the obtained nanocomposites were investigated by X-ray, differential-thermal, thermogravimetric and IR spectroscopic analyzes. It has been found that nanomodified polycaproamide has a higher crystallinity and higher thermal stability than the original PA-6, and is characterized by considerably higher melt fluidity. The presence of polyvinylpyrrolidone and exfoliated montmorillonite in the nanocomposite structure was experimentally confirmed.
