Seed Oil Based Highly Branched Environment Friendly Polyester Resin/Clay Nanocomposites [Elektronische Daten] [Uday Konwar, Niranjan Karak] To develop a high performance environment friendly material, highly branched polyester/clay nanocomposites have been prepared from Mesua ferrea Linn seed oil-based polyester resin and hydrophilic bentonite nanoclay. The prepared nanocomposites were characterized by Fourier transform infra-red spectroscopy, X-ray diffractometer, scanning electron microscope, transmission electron microscope and rheological studies. Partial exfoliation of clay layers by the polymer chains with good interfacial interactions was observed in the nanocomposites. The formation of delaminated nanocomposites was manifested through the enhancement of tensile strength, scratch hardness, chemical resistance, impact resistance, thermostability, etc. The results show enhancement of three times in tensile strength and 18°C in thermostability by inclusion of 5wt% nanoclay as compared to the pristine polymer. By the influence of 5wt% nanoclay four times enhancement in elongation at break as compared to the pristine polymer was noticed. Thus these nanocomposites have the potential to be used in many advanced applications.
