Enhanced Thermal and Mechanical Properties of Cardanol Epoxy/Clay-Based Nanocomposite through Girard’s Reagent

“…In comparison, the FTIR spectrum of G-clay displays a newly observed characteristic peak at 1620 cm −1 , distinguishing it from the original clay. This peak is assigned to the stretching vibration of primary amines present in the Girard’s reagent incorporated within the G-clay [ 44 ]. Characteristic bands at 1492 cm −1 and 1424 cm −1 can be attributed to the asymmetric and symmetric bending of the methyl group of Girard’s reagent [ 43 ].…”

“…In Figure 2a, the XPS electron spectra of G-clay are presented. Upon introducing Girard's reagent into the clay lamellae, characteristic peaks attributed to carbon (C 1s) and nitrogen (N 1s) atoms, which are intrinsic to the Girard's reagent, emerged in the full-spectrum scan of Gclay [44]. Notably, the characteristic peaks originating from the sodium (Na 1s) atom X-ray photoelectron spectroscopy (XPS) was employed to characterize both the original clay and G-clay samples.…”
