“…The ternary composites exhibited large specific capacitance, good rate capability and high cycling stability, superior to those of individual components (mixed transition metal oxides, RGO, PANI) and corresponding binary hybrids (graphene/mixed transition metal oxides, mixed transition metal oxides/PANI, and graphene/PANI). Moreover, A symmetric supercapacitor device using the as-obtained ternary hybrids exhibited a maximum energy density of 13.5 W h kg À1 [230], comparable to that of majority symmetric supercapacitor devices reported in recent years such as 3D MnO 2 / graphene [195], MnFe 2 O 4 /graphene [232], and ternary graphene/ MnO 2 /CNTs (Fig. 11d) [233].…”

“…Compared with the standard diffraction peak characteristic spectral lines of SrFe 12 O 19 , the diffraction peak of R-GO/SF nanocomposites shifts towards lower 2θ and the diffraction peak of GO in the R-GO/SF nanocomposites disappeared. Based on previous reports [33], GO is effectively reduced to R-GO under the effect of reducing agent hydrazine hydrate, and the lamellar dispersion of R-GO in R-GO/SF composites is well. The characteristic diffraction peak of SrFe 12 O 19 in the R-GO/SF composites shift slightly towards lower 2θ, in which it can be deduced that SrFe 12 O 19 has been successfully assembled on the surface of R-GO sheets [34, 35].…”

Strontium ferrite nanoparticles were prepared by a coprecipitation method, and reduced graphene oxide/strontium ferrite/polyaniline (R-GO/SF/PANI) ternary nanocomposites were prepared by in situ polymerization method. The morphology, structure, and magnetic properties of the ternary nanocomposites were investigated by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), TEM, Raman, and VSM. The microwave-absorbing properties of the composites were measured by a vector network analyzer. The XRD patterns show the single phase of strontium hexaferrite without other intermediate phases. TEM photographs reveal that strontium ferrite nanoparticles are uniformly dispersed on the surfaces of R-GO sheets. The R-GO/SF/PANI nanocomposite exhibited the best absorption property with the optimum matching thickness of 1.5 mm in the frequency of 2–18 GHz. The value of the maximum RL was −45.00 dB at 16.08 GHz with the 5.48-GHz bandwidth. The excellent absorption properties of R-GO/SF/PANI nanocomposites indicated their great potential as microwave-absorbing materials.

“…A ternary manganese ferrite/graphene/polyaniline (MGP) composite reported by Xiong et al 12 was synthesized through a facile two-step strategy, and an improvement in the electrochemical capacitance and cycling stability was observed. Qi et al 13 attempted to improve the performance of PANi by preparing PANi/non-woven fabrics using an in situ polymerization method.…”

Crystalline nanocellulose was prepared from Semantan bamboo (Gigantochloa scortechinii) via acid hydrolysis and was used to synthesize a nanocomposite of polyaniline/crystalline nanocellulose (PANi/CNC) via in situ oxidative polymerization of aniline in the presence of crystalline nanocellulose. The electrochemical properties of the nanocomposite were studied using a modified PANi/CNC electrode via cyclic voltammetry, and higher current response was observed for the PANi/CNC-modified electrode compared to that for the modified electrode with PANi. The results obtained from EIS displayed lower value of R ct for the PANi/CNCmodified electrode, indicating that the incorporation of CNC into the PANi structure could enhance the electron transfer rate. The characteristic peaks of PANi and CNC were observed in the FTIR spectra of the nanocomposite, indicating the incorporation of CNC inside the nanocomposite structure. Moreover, in the XRD diffractogram, lower crystallinity was observed at the 2 theta values of 22.6 and 16.1 for PANi/CNC compared to that for pure CNC. The FESEM images showed high porosity of the nanostructure with no phase separation, revealing the homogenous polymerization of the monomer on the surface of the crystalline cellulose. Aggregation of PANi particles was observed with the increasing aniline concentration.
