“…In addition to polypyrrole and polyaniline, polythiophene (PTH) and its derivatives are very beneficial for improving composites’ absorbing properties due to their unique electrical conductivity, favorable environmental and thermal stability, solubility, low cost, and high mechanical strength. Moghaddam et al [ 62 ] prepared PTH/PTH/SrFe 12− x (ZrZn) 0.5 x O 19 ( x = 0.9) nanocomposites. The nanocomposites prepared by the coupling interaction between SrFe 12− x ( ZrZn) 0.5 x O 19 ( x = 0.9) particles and PTH could achieve an effective microwave absorption of more than 95%.…”

With the extensive application of electrical and wireless equipment, several electromagnetic pollution‐related issues have emerged. Therefore, the manufacturing of absorbing materials has become important to electromagnetic pollution. Ferrite is a common absorbing material; its single absorbing mechanism and narrow absorbing frequency band resist the wider usage as an ideal absorbing material. Adding different materials to ferrite has become a popular way to enhance its microwave absorption properties. Herein, the recent research on ferrite multicomponent microwave absorbing composites is summarized. For ferrite binary composite absorbing materials, the research progress of ferrite and graphene, carbon nanotubes, carbon fiber and other carbon materials, ferrite and polypyrrole, polyaniline and other polymer materials, and ferrite and MXene composites is introduced. In addition, the advancement of ferrite ternary absorbent materials research is also discussed. The growing development trend of ferrite composite absorbing materials is finally summed up, and the prospects of fabricating the “thin, light, wide, and strong” ferrite absorbing materials are put forward.

Graphene foams (GFs) prepared via a hydrothermal method can be vacuum-dried directly without the need for freezing by adding naphthalene to the graphene hydrogels. By optimizing the GF preparation process, it is also possible to adjust the GF’s dielectric properties by varying the amount of naphthalene added. Based on the comparison results, it was observed that controlling the addition of naphthalene could also modify the internal structure of GF and effectively regulate its dielectric properties. GF-80, synthesized with 80 g of naphthalene, exhibited exceptional microwave absorption (MA) performance. At a mass content of only 2% and a matching thickness of 3.38 mm, a minimum reflection loss (RLmin) of −55.89 dB was achieved. Moreover, GF-80, with a thickness of 2.31 mm, was shown to achieve a bandwidth of RL less than −10 dB across 6.88 GHz.

“…Nowadays, polythiophene (PTh), polypyrrole (PPy), polyaniline (PANI), and other conducting polymers have been drawing much attention in the application of photocatalysis owing to their broad light absorption and effective carrier separation efficiency. − Conducting polymers possessing conjugated π–e – systems may lead to an increase in the absorption range of the spectrum and thus become a synergistic component in newly designed functional composites along with other semiconducting materials . Conducting polymers such as PPy, PANI, and PTh can act as excellent sensitizers due to their conjugated π–e – system making it easier for electrons–holes to move within the framework.…”

Polyoxometalate-based all-inorganic three-dimensional (3D) frameworks have recently attracted attention as a unique class of materials due to their unique physicochemical properties and a wide field of application with excellent prospects. We herein synthesized a novel all-inorganic 3D framework material based on cobalt-substituted Silverton-type polyoxometalate,) and Co(NO 3 ) 2 •6H 2 O as starting materials in a hydrothermal reaction via a decomposition−reassembly route together with the rational adjustment of pH values. Co 9 W 10 has been structurally characterized using single-crystal X-ray diffraction. Photocurrent response, band-gap (E g ) value, and the VB-XPS spectrum have been measured to reveal the semiconducting property of Co 9 W 10 . Furthermore, we synthesized x% PTh/Co 9 W 10 composites (PTh = polythiophene, x = 0.5, 1, 2, 5) for photodegradation of tetracycline hydrochloride (TH) to evaluate the photocatalytic activities of title composites. Due to the optimal molar ratio of hybrids and matching energy levels, 2% PTh/Co 9 W 10 composites show the best photocatalytic activities among these composites.
