Anandhan, S.Patil, H.G.Raj, M.A.2026-02-052012Advanced Science Letters, 2012, 6, , pp. 134-14019366612https://doi.org/10.1166/asl.2012.2020https://idr.nitk.ac.in/handle/123456789/27010For the first time, nanocomposites have been synthesized from ethylene-vinyl acetate-carbon monoxide terpolymer (EVACO) by adding 1, 3 and 5 wt% of organo-montmorillonite (O-MMT) by solution blending. By highresolution transmission electron microscopy (HRTEM), EVACO has been found to crystallize in nano-dimensions. Wide angle X-ray diffraction (WAXRD) reveals the predominance of intercalated morphology in these nanocomposites, while TEM micrographs reveal the co-existence of exfoliated and intercalated morphologies for these hybrids at all levels of clay loading. O-MMT hinders crystallization of EVACO, and due to this, optical transparency is not affected even at 5% O-MMT loading in these nanocomposites. By incorporation of 5% O-MMT, tensile strength of EVACO increases by 660%; while elongation at break decreases by 500%. Addition of O-MMT significantly reduces the thermal stability of these nanocomposites. © 2012 American Scientific Publishers All rights reserved.Multiple melting endothermOrganoclayPolymer nanocomposites (PNCs)Thermal analysis
