- Abstract
The CoO @ phenol formaldehyde resin (PFR) cube-like nanocomposites are prepared by one-step hydrothermal process at 120-180 °C for 3-9 h. Co(NO)·6HO, hexamethylenetetramine (HMT), and phenol are used as precursors in water solvent. Any adventitious oxidants and additives are not presented. The transmission/scanning electronic microscope (TEM, SEM) images show as-obtained typical samples are consisted of cube-like CoO as core and PFR as shell. The X-ray diffraction (XRD) data indicate the samples are consisted of cube-phase CoO with amorphous PFR. Fourier transform infrared spectra (FTIR) further confirm CoO and PFR are contained in the samples. Room-temperature vibration magnetic strength measurements (VMS) indicate that the antiferromagnetic properties of core-shell nanocomposites evidently differ from the naked-CoO nanoparticles.
