Abstract

This research presents an analysis of castor oil-based polymer nanocomposites that can be used for numerous commercial applications. Due to the versatile chemical structure of castor oil, it can replace the petrochemical products and hence can be optimized as nontoxic bioresource for the production of nanocomposites with the incorporation of nanofillers in small quantities. It can be directly used as polyol resource without any chemical alteration for synthesis of polyurethane (PU) nanocomposites. The prepared PU nanocomposites were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, wide angle X-ray diffraction, transmission electron microscopy (TEM), and mechanical properties. The compositional and structural studies indicate the formation of PU linkages and well dispersion of clay and multiwalled carbon nanotubes between the polymer–nanofiller phase, as shown by the morphological analysis using TEM. Also, there is an increase in the tensile strength and Young’s modulus values with the increase in the filler content.
