Simple Method for the Preparation of Composites Based on PA6 and Partially Exfoliated Graphite

Abstract EN

In the present work, the preparation of composite systems based on polyamide 6 (PA6) and exfoliated graphite was attempted by applying a simple procedure, which consists of a preliminary dispersion/exfoliation of graphite in the monomer, namely, ɛ-caprolactam (CL), and a subsequent polymerization of the above system.

Atomic force microscopy (AFM) demonstrated specific interactions between CL and graphite surface.

The dispersion of graphite in the monomer and polymer was assessed by scanning (SEM) and transmission (TEM) electron microscopy, while mechanical tests allowed to evaluate the influence of graphite on the polymer properties.
