SOLUTION BLENDING PROCESS FOR THE FABRICATION OF NYLON6-MONTMORILLONITE NANOCOMPOSITES

摘要

In general the present disclosure relates to Nylon 6/montmorillonite clay nanocomposites with enhanced mechanical properties that have been prepared primarily by solution compounding. A major challenge in producing the Nylon 6/montmorillonite clay nanocomposites is associated with the exfoliation and dispersion of the clay particles within the polymer matrix. This disclosure presents compositions and methods for obtaining highly or fully exfoliated nylon 6/montmorillonite nanocomposites not only for organically modified clays with known compatibility with nylon 6 (Cloisite 30B), but also for clays with low/no compatibility with nylon 6 (Cloisite 15A and Na—MMT) through solution compounding.

1. A nanocomposite comprising the reaction product of:
nylon 6; and, a montmorillonite clay comprising an inorganic ion or an organic surfactant with the structure of an ammonium ion (NR4+), wherein R represents an alkyl or aryl group and excludes hydroxyethyl groups, wherein the clay has at more than 200 platelets/μm2 in the nanocomposite.
