Ethylene Vinyl Alcohol Nanocomposite Films: Comparison of Their Properties at Various Equibiaxial Stretching Ratios.
Ethylene vinyl alcohol (EVOH) hybrid films containing 3 wt% Cloisite 10A were stretched equibiaxially at various stretching ratios in the range 100-200% to investigate the thermo-optical properties and oxygen permeabilities of the films in detail. The effects that variations in the equibiaxial stretching ratio had on clay dispersion and morphology were also determined. The optical transparency and oxygen barrier property were almost constant irrespective of the increase in the stretching ratio from 125 to 200%.
