Extensive development in electronics and allied sectors has led to unseen pollution termed electromagnetic interference (EMI). Motivated by its aftereffects, the fabrication of efficient EMI shielding has become a major area of research. This review presents a detailed analysis of very recent trends in various hybrid materials based on polymers, cement, concrete, paints, and so on with diverse filler inclusions for electromagnetic shielding applications. This paper also focuses on the origin and effects of electromagnetic (EM) radiation, the shielding mechanism, and the suitability of the hybrids, various fabrication techniques, characterization; and so on. Fiber-reinforced polymer composites, metal films, microfilms, inks, paints, multiple laminated composites, foams, aerogel-based polymer composites, textiles, and so on are discussed. Newly developed materials like MXene, borophene, semiconducting filler-based hybrid materials are also covered. Finally, an attempt is made, to sum up, the major challenges faced in the design and development of polymer materials for EMI shielding applications.

“…Galvanic black coatings are used to absorb light in optical devices and collectors, which convert light energy into heat, as well as protective and decorative coatings for various products [1][2][3]. In most cases, black chrome and nickel coatings are used for these purposes [4][5][6][7][8][9][10]. Known disadvantages of chromium plating processes are the difficulty of implementation and high energy intensity, due to the need to heat solutions and losses due to the side reaction of hydrogen evolution.…”

Absorbing surfaces of solar receivers are coated with black chrome, which provides the surface of steel or aluminum tubes with good absorption properties. However, the chrome coating does not protect well against corrosion because of its high porosity and high internal stresses, which cause a cracking of coatings. In this paper, we investigated two methods for formation of black coatings on chemically formed Ni-P layers: etching in nitric acid and anodic treatment in a phosphoric acid solution. It was found that in the course of processing the black coatings, their roughness and porosity increase. It was shown that nickel oxides NiO and Ni2O3 and nickel phosphates are presented in the coating composition. It was established that the heat treatment increases the wear resistance and protective ability of black coatings.

“…Many strategies have been explored to design a near-perfect black coating having emissivity and absorption equal to 1. , A perfect black coating absorbs all the incident light independent of angle and wavelength . Ultrablack coatings find applications in diverse areas such as solar collectors, infrared cameras, spectroscopic equipment, space telescopes, satellites, biomedical devices, photo actuators, and stray light suppression. − Various techniques such as nanotexturing, lithography, electrodeposition, and metamaterial are used to fabricate optical absorbers. − Most of these techniques are complex and are able to manufacture absorbers with efficient absorption in a narrow wavelength range. Recently, an optical gradation scheme has been employed to absorb incident light in the broader wavelength range of 300–2000 nm. − However, reflections originating from the interfaces between layers are a major shortcoming of the optically graded coatings …”

Near-perfect black surfaces are desirable in many applications, including from space telescopes and satellites to energy harvesting and biomedical devices. Carbon nanostructures have emerged as potential candidates for fabricating ultrablack optical absorbers. Here, we have studied the structure-dependent light absorption capacity of carbon nanotubes in the broadband region of UV−vis−NIR. Four types of carbon nanotube (CNT) structures, noodle CNTs, spring CNTs, vertically aligned carbon nanotubes (VACNTs), and flower carbon nanotubes (FCNTs), are fabricated using the thermal chemical vapor deposition (CVD) technique. The light-trapping capacity of noodle CNT, spring CNT, VACNT, and FCNT is ≥94%, ≥95%, 98%, and ≥99.97%, respectively, in the UV−vis−NIR wavelength range. Varying the absorption of incident radiation in CNTs has been attributed to various structure-dependent parameters such as multiple scattering, light trapping sites, multiple length scales, and optical path length. It is shown that hierarchical structure imparts near perfect blackbody characteristics (absorption, >99.98%; emissivity, −0.98) to FCNTs. In addition, the superhydrophobic and self-cleaning behavior of VACNTs and FCNTs makes them suitable candidates for solar and antibacterial applications.
