Abstract: | Ethylene propylene diene terpolymer (EPDM)/MgAl layered double hydroxide (LDH) nanocomposites have been synthesized by solution
intercalation using organically modified LDH (DS-LDH). The molecular level dispersion of LDH nanolayers has been verified
by the disappearance of basal XRD peak of DS-LDH in the composites. The internal structures, of the nanocomposite with the
dispersion nature of LDH particles in EPDM matrix have been studied by TEM and AFM. Thermogravimetric analysis (TGA) shows
thermal stability of nanocomposites improved by ≈40 °C when 10% weight loss was selected as point of comparison. The degradation
for pure EPDM is faster above 380 °C while in case of its nanocomposites, it is much slower. |
