Novel nanocomposite films based on poly(ethylene-co-acrylic acid) (PEAA) and zinc montmorillonite (Zn2+-MMT) were fabricated using a solution casting method with water as the solvent. Transmission electron microscopy indicated that Zn2+-MMT was distributed finely in the PEAA matrix. X-ray diffraction indicated that an ion exchange process occurs between Zn2+-MMT and PEAA. The nanocomposites filled with a low Zn2+-MMT loading increased the tensile strength and elongation at break. The significant improvements in these mechanical properties were attributed to the fine dispersion of Zn2+-MMT in the polymer and the covalent interaction between the polymer chains and Zn2+ cations. Thermogravimetric analysis and differential thermal calorimetry confirmed that PEAA formed a network through the presence of Zn2+ cations. A poly(ethylene-co-acrylic acid) zinc salt (PEAAZn) film by hot pressing was introduced for comparison. Zn2+-MMT improved the mechanical properties of the PEAA significantly compared to that of PEAAZn.
