“…[ 48–50 ] The crystalline state of carbon in SCFs was almost the same between SCF@GO and SCF@CNTs hybrids as there is negligible difference between the values of R for both cases. [ 51 ] This confirmed that both GO and CNTs were successfully assembled onto the surface of SCFs, which was also corroborated by SEM.…”

Multiscale carbon‐based hybrids are obtained by decorating either graphene oxide (GO) or carbon nanotubes (CNTs) on the surface of short carbon fibers (SCFs) via a facile layer‐by‐layer self‐assembly process. Hybridization of polytetrafluorethylene (PTFE) fibers and multiscale SCF hybrids is used to improve the tribological properties of polyphenylene sulfide (PPS)‐based composites. Results show that the presence of multiscale SCF hybrids can significantly enhance the compatibility between the host matrix and fillers. Scanning electron microscopy (SEM) observations reveal that the construction of an interlocking network structure formed by PTFE fiber and multiscale SCF hybrids is likely the contributing factor, which leads to better tribological properties of the resulting composites. The PPS/PTFE/SCF@GO20 composite exhibits the best tribological performance, with a friction coefficient of 0.165 and specific wear rate of 3.12 × 10−5 mm3 Nm−1, which are ≈73.6% and 99.6% lower than those of pure PPS, respectively.

“…On the high-resolution spectrum of O 1 s of S-5 (Fig. 4 d), three characteristic peaks of 531.5, 530.6, and 529.0 eV can be observed, corresponding to the water or O adsorbed on the sample surface, oxygen vacancies and metal-O (Ni–O/Co–O) respectively [ 49 , 50 ]. Co 2p can be fitted to six distinct characteristic peaks (Fig.…”

Layered double hydroxides (LDHs) have a special structure and atom composition, which are expected to be an excellent electromagnetic wave (EMW) absorber. However, it is still a problem that obtaining excellent EMW-absorbing materials from LDHs. Herein, we designed heterostructure NiCo-LDHs@ZnO nanorod and then subsequent heat treating to derive NiCo@C/ZnO composites. Finally, with the synergy of excellent dielectric loss and magnetic loss, an outstanding absorption performance could be achieved with the reflection loss of − 60.97 dB at the matching thickness of 2.3 mm, and the widest absorption bandwidth of 6.08 GHz was realized at 2.0 mm. Moreover, this research work provides a reference for the development and utilization of LDHs materials in the field of microwave absorption materials and can also provide ideas for the design of layered structural absorbers.

“…The peak at 1000 cm −1 belonged to the C-O stretching mode. While the measurement of XRD clearly indicates that the TiO 2 is highly crystallized, this phenomenon may be described as the formation of C-O-Ti bond in the TiO 2 /graphene system [34,35]. The FT-IR spectrum of Ag/TiO 2 /graphene is similar to that of TiO 2 / graphene, which suggests that loading Ag nanowires will not change the chemical structure of TiO 2 /graphene nanocomposite.…”

In this paper, a novel Ag nanowires/TiO 2 nanosheets/graphene nanocomposite was fabricated via a facile method of hydrothermal and calcination, and then the water treatment performance of it was evaluated for methylene blue (MB) and Escherichia coli removal. The as-prepared Ag nanowires/TiO 2 nanosheets/graphene nanocomposite was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), UV-visible diffuse reflection spectroscopy (DRS), molecular dynamics simulation, and gas chromatography-mass spectrometry (GC-MS). All data revealed that the Ag/ TiO 2 /graphene nanocomposite showed a rich cell structure. The photocatalytic activity of Ag/TiO 2 /graphene nanocomposite is higher than those of pristine TiO 2 nanosheets and TiO 2 /graphene nanocomposite. Under optimized conditions, the degradation efficiency was 100% and 71% for MB (30 mg/L) and with 10 mg Ag/TiO 2 /graphene nanocomposite under UV and visible light irradiation for 2 h, respectively. Ag/TiO 2 /graphene also showed excellent bacteria-killing activity. Meanwhile, the Ag/TiO 2 / graphene nanocomposite exhibited microstructure stability and cyclic stability. The water treatment performance was enhanced mainly attributed to the excellent adsorption performance of graphene and the high efficiency in separation of electron-hole pairs induced by the remarkable synergistic effects of TiO 2 , Ag, and graphene. On the basis of the experimental results, the photocatalytic mechanism and MB degradation mechanism were proposed. It is hoped that our work could avert the misleading message to the readership, hence offering a valuable source of reference on fabricating composite photocatalyst with stable microstructure and excellent performance for their application in the environment clean-up.
