Abstract
Thin films of nylon-12 with 10% nanoclay content were prepared by various mixing and extrusion methods. The films were then assessed for chemical permeability and tensile strength and also by FTIR. TEM images were taken of film cross-sections. Materials mixed by batch blending and single-screw extrusion prior to extrusion as a film showed incomplete exfoliation of the nanoclay particles and poor dispersion. Materials mixed by twin-screw extrusion showed better exfoliation and dispersion, but also showed significant breakdown in nanoclay platelet size. FTIR spectra showed a correlation between dispersion and peak height for the 1030 cm-1 clay peak. Exfoliation and dispersion appear more important than platelet size to both the strength and barrier properties of the thin films.
