Conducting polymer-nanocomposite has potential applications in optoelectronic devices. This paper presents a novel composite consisting of polypyrrole (PPy), polyaniline (PANI), graphene oxide (GO), and multiwall carbon nanotube (MWCNTs) deposited on MnO2/Fe3O4/n-Si structure, resulting in a structure that is PPy-PANI-GO-MWCNTs composite/MnO2/Fe3O4/n-Si. This structure is investigated by scanning electron microscope, X-Ray diffraction, and Raman spectroscopy. PPy-PANI-GO-MWCNTs composite/MnO2/Fe3O4 /n-Si structure is used in manufacturing electronic devices like diodes, which have tunneling behavior at low voltage, though at voltage more than the voltage (V)= 0.5 V, the diode behavior as an ordinary diode. PPy-PANI-GO-MWCNTs composite/MnO2/Fe3O4/n-Si structure has a very high conductance reach of (S), and capacitance reaches -11 F. The electrical and dielectrically properties of this structure PPy-PANI-GO-MWCNTs compositeMnO2/Fe3O4/n-Si were done.

“…Many researchers have demonstrated that new features may be induced by combining two or more materials in a controlled ratio which is known as the composite structures process, which has recently become an interesting topic of research [1][2][3][4]. Composites have been used in a variety of applications including sensors, electrodes, photocatalysts, fuel cells, non-volatile magnetic memories, and data storage device magnetic heads [5][6][7][8].…”

In this work, nanocomposites were prepared with different weight ratios based on the formula (1-x)ZnO + (x)Fe3O4, where x = 0.01, 0.03, 0.05, 0.07 and 0.09. The structure, morphology, optical, and magnetic properties were examined by X-ray diffraction, UV VIS-NIR diffuse reflectance spectroscopy, high-resolution transmission electron microscopy (HRTEM), and vibrating sample magnetometer (VSM). The X-ray diffraction (XRD) results confirm the phase purity formation of Fe3O4-ZnO nanocomposites. The transmission electron microscopy (TEM) exhibited the prepared powders are nanoparticles with the spherical shapes of Fe3O4 and nanorod for ZnO. UV VIS-NIR diffuse reflectance measurements showed that the Fe3O4 modified the optical properties of ZnO. Results of the vibrating sample magnetometer (VSM) display a superparamagnetic characteristic of Fe3O4 and ferromagnetic behavior for nanocomposites. The magnetization and remanence magnetization of nanocomposites increases with Fe3O4 content.

The pure TiO2 and TiO2/xCoFe2O4 nanocomposites (0, 2, 4, and 6 wt. %) were synthesized using the sonomechanical method at room temperature. The prepared specimens were studied by scanning electron microscopy (SEM), energy-dispersive X-ray techniques (EDX), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and ac conductivity measurements. The sample exhibited homogeneous and well-distributed spherical nanoparticles of visible surface edges with average grain size ranging from 100 to 200 nm, as shown in the SEM micrograph. Raman spectra analysis showed the characteristic band for TiO2 at 141.2, 233.08, 447.13, 609.55, and 639.4 cm−1. The FTIR confirmed the interaction of CoFe2O4 and TiO2 reflecting the successful formation of nanocomposites. Compared to pristine TiO2, both the dielectric constant (ε') and conductivity were boosted by the inclusion of CoFe2O4. The behavior of the exponent factor (S) with temperature demonstrates that the conduction mechanism is the correlated barrier hopping (CBH) mechanism. The investigation of complex electric modulus established that the vertiginous nanocomposite had a non-Debye-type relaxation. The observed properties prove that TiO2/ xCoFe2O4 (x = 0, 2, 4, and 6 wt. %) nanocomposites are very functional for electric storage applications.
