WebStearic acid: Stearic acid is a saturated fatty acid and a surfactant (literally, an amphiphilic,“surface acting”, chemical that lowers surface tension at the interface between molecules or groups of molecules that do not mix well) that has excellent emulsifying and lather stabilizing properties. Web1 day ago · Meanwhile, the absorption peak at 881 cm −1 was attributed to the C−C skeleton vibration of the stearic acid (Fig. 7 (d)), and the absorption peak at 776 cm −1 was ascribed to the bending vibration of −(CH 2) n − groups [35]. All the results indicate that the stearic acid has successfully decorated the porous nickel layer surface.
