Waterborne epoxy-clay nanocomposites were prepared by encapsulation of organoclays in epoxy latex particles via phase inversion emulsification. The organoclays were exfoliated in the epoxy backbone before compounding with a hardener and subsequently dispersing in water. The encapsulation of clay platelets into the waterborne epoxy latex particle resulted in an exponential increase in particle size, from 5 to 10 times at a clay loading of only 1-2 wt%, respectively. The XRD patterns and TEM images show that clay platelets were well intercalated and exfoliated in the epoxy matrix. The gas barrier performance of the epoxy-clay nanocomposite strongly depended on the kind of organoclay. The best oxygen barrier efficiency was approximately 14% at 2 wt% clay loading.
