Researchers from University of Technology, Baghdad, have synthesized castor oil-based polyurethanes–organoclay (COPUs-Cloisite 30B) nanocomposites by mixing polypropylene glycol polyol and dehydrated castor oil (15 %), with C30B nanofillers at different weight percentages. Various analyses such as Fourier Transform Infrared Spectroscopy, Fourier scanning Electron Microscopy, Scanning Electron Microscopy and X-ray diffraction were performed to evaluate the physico-chemical properties of COPUs-Cloisite 30B. Thermal stability and tensile strength were found to improve upto ~30 C and ~240% respectively, with 5 wt% of C30B . These improved properties allow it to be used in coatings, adhesives and automotives.
