The formulation of polymer with embedded magnetic nanoparticles results in promising nanocomposites for smart and analytical applications. Nanocomposites containing polyacrylonitrile (PAN) and different mass contents of strontium hexaferrite (SFO) were prepared using the casting method. The nanocomposite samples were characterized by using different techniques such as field-emission scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. Dielectric investigations of SFO/PAN nanocomposites showed that the permittivity and conductivity are considerably enhanced as the content of SFO increased. Optical properties revealed that the absorption and transmittance spectra were significantly affected by adding SFO nanoparticles to the PNA polymer matrix. To investigate the magnetic properties of the nanocomposite samples, the vibrating sample magnetometer was used. The magnetic hysteresis loops illustrated the ferromagnetic nature of SFO/PAN nanocomposites. Different magnetic parameters were given, and they depend on the content of PAN in the nanocomposites.

“…The sol-gel method was also used to prepare different ceramics, for instance, as reported earlier [42,43]. In which, M-type hexagonal ferrites Ba 1-x Sr x Fe 12 O 19 , where x ranged from 0 to 0.75, were synthesized [42]. The as-prepared ceramics were characterized by different techniques.…”

Sol-Gel Method - Recent Advances

Two main approaches for nanomaterials fabrication are the top-down and the bottom-up methods. The first is limited to mechanical grinding, thermal evaporation, ion sputtering, arc discharge, pulsed laser ablation, and other physical and chemical vapor deposition. These routes are costly, consume higher energy, and require complex technology such as ultrahigh vacuum. The bottom-up methods refer to the production of complex nanostructured materials from atoms and molecules. This approach is relatively simple and low in cost. However, it requires a good knowledge of the optical properties of the particles and their modifications when the particles are integrated with nanostructures. One of the widest bottom-up methods is the sol–gel. It involves a solution or sol (single-phase liquid) that undergoes a sol–gel transition (stable suspension of colloidal particles). In this chapter, we throw light on the history of sol–gel, its advantages, and limitations, operating this method for the production of different types of nanomaterials in the form of powders or thin films. In addition, some applications of the sol–gel-derived nanosized materials will be discussed.
