Abstract
Thevetia peruviana commonly known as yellow oleanda or lucky nut seed oil was harvested in EmureEkiti, southwestern Nigeria. The extraction of the seed oil was carried out using n-hexane in a soxhlet extractor. The seed oil with high contents of 18:1 (48.24%), 16:0 (22.25%), 18:2 (19.76%) fatty acids and having the following physico-chemical parameters (I.V, 75.4; S.V, 192.5; P. V, 1.9; A.V, 2.0; specific gravity, 0.91175; density, 0.90905. The seed oil was used in the preparation of diethanolamide. The diethanolamide was subsequently used in the preparation of polyurethane/clay nanocomposite. The formation of the hybrid polymeric coating was monitored and confirmed using Fourier Transform Infrared Spectroscopy (Ff-IR), Nuclear Magnetic Resonance (IH-NMR and 13C-NMR), Electronspin ionization-mass spectroscopy (ESIMS), X-ray diffraction spectroscopy (XRD). The thermal stability of the product was studied by Thermal gravimetic analyser (TGA), Dynamic and mechanical thermal analyser (DMTA), Differential scanning calorimetry (DSC).
