P-phenylenediamine-benzoquinone Schiff base Ag(I) complexes chemically bonded to few-layered graphene as flexible materials for electromagnetic studies

A novel electromagnetic material has been synthesized through P -phenylenediamine-benzoquinone (PB) Schiff base Ag(I) complexes chemically bonded to few-layered graphene (FLG). The structure of the samples was characterized by Fourier transform infrared spectroscopy and X-ray diffraction. The shape and size were observed by scanning electron microscopy and transmission electron microscopy. The conductive properties were tested by a four-probe conductivity tester at room temperature, and the magnetic properties of the samples were tested with the vibrating sample magnetometer. These results show that the PB Schiff base Ag(I) complexes are chemically bonded onto the FLG layers. The conductivity, magnetic saturation, residual magnetization, and coercive force of the composite achieve 5.86 S cm −1 , 1.47 emu g −1 , 0.26 emu g −1 , and 208.3 Oe, respectively. Finally, based on the experimental results, the probable formation, electronic transmission, and magnetic mechanism have also been investigated.
