Dynamic modulus (G′) of Ca (top) and clay (bottom) nanocomposites at 110 °C. The solid lines are fits to the generalized Maxwell model (seven modes) with the parameters given in Table II .
Extensional results for EVA at different temperatures. Full lines are MSF predictions and dashed lines are obtained from linear viscoelastic data. Experimental and modeling results at T = 190 °C are vertically multiplied by a factor 1/3 and displayed.
Shear and extensional viscosities of EVA, clay 2.5 and all Ca compositions at 110 °C. Full lines are viscosity prediction by the MSF model. Dashed lines are obtained from linear viscoelastic data.
Extensional viscosity of clay nanocomposites at 110 °C. Dashed lines are obtained from linear viscoelastic data. For these clay concentrations (5, 7.5, and 10 wt. %), the viscosity predictions by LVE go beyond the experimentally obtained viscosities.
TEM images for Ca (left) and clay (right) nanocomposites at 5 wt. %.
Relative intensity of the third harmonic to the first one (I 3/I 1) obtained in LAOS as a function of strain for EVA and different nanocomposites at 110 °C and 0.05 Hz.
Compositions of the nanocomposites produced.
Relaxation spectra for all the composition using a seven-mode Maxwell model with partial moduli (gi) and relaxation times (λi) obtained from SAOS data of Mahi and Rodrigue (2012b) .
