Abstract: Zinc-containing polyurethane-urea/organoclay nanocomposites with varying contents of organophilic bentonite (OBNH) were prepared by solution intercalation. OBNH was obtained through an ion-exchange reaction of bentonitewith oleylmethylbis (2-hydroxyethyl) ammonium chloride. Zinc-containing polyurethane-ureas were synthesized by reacting hexadentate Schiff base zinc complexes with isocyanate-terminated prepolymers. The successful attainment of intercalated nanocomposites was confirmed by X-raydiffraction (XRD) and transmission electron microscopy (TEM) analysis. Thermogravimetric analysis (TGA) results indicated that at high temperatures (300 – 1000°C) the Zinc-containing polyurethane-urea/organoclay nanocomposites had a lower % weight loss than Zinc-containing polyurethane-urea prepared without organoclay.
