“…[1,2] In particular, the infrared (IR) shielding materials gain more and more attention in the scientific community because they can act as the barriers or filters against IR radiation and resulting heating effects. [3,4] This unique property can be effectively used in the application like wearable IR shield, [5] solar filters, [6,7] solar collectors, [8] optical fibers, [9] stealth technology, [10][11][12][13] and so-called smart windows which aim to limit or increase the indoor temperature during summer or winter season, respectively.

In order to use the infrared (IR) radiation shielding materials, they should take a form of thin film coatings deposited on glass/polymer substrates or be used as fillers of glass/polymer. The first approach usually suffers from several technological problems. Therefore, the second strategy gains more and more attention. Taking into account this trend, this work presents the usage of iron nanoparticles (Fe NPs) embedded into the poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) films as the shielding material in near-infrared (NIR) and mid-infrared (MIR) region. The performed investigations show that the transmittance of copolymer films decreases with increasing content of the Fe NPs inside them. It is found that the average fade of IR transmittance for 1, 2.5, 5, 10, and 50 mg of Fe NPs is about 13%, 24%, 31%, 77%, and 98%, respectively. Moreover, it is observed that the PVDF-HFP films filled in the Fe NPs almost does not reflect the NIR and MIR radiation. Hence, the IR shielding properties of the PVDF-HFP films can be effectively tuned by the addition of proper amount of the Fe NPs. This, in turn, shows that the PVDF-HFP films filled in the Fe NPs constitute a great option for IR antireflective and shielding applications.

With the increasing problems of electromagnetic interference and electromagnetic radiation, electromagnetic wave absorption (EMWA) materials have received considerable attention in civil and military fields. Among various EMWA materials, one-dimensional (1D) nanomaterials are recognized as a very promising candidate because of their unique aspect ratio, special shape anisotropy, large specific surface area, and simple manufacturing process. Herein, this paper presents a comprehensive review of recent research progress of 1D nanomaterials for EMWA applications, with a special focus on the advances in general preparation strategies and microscopic structure construction. Furthermore, the current challenge and future prospect of 1D electromagnetic absorbers are proposed, which should provide some guidelines for the design of advanced EMWA materials.

“…Metals such as copper, silver, gold, and metal composite materials can effectively reflect EM radiation. These materials are usually coupled or mixed with carbon materials but inevitably lead to secondary pollution, which limits their broader application. − Carbon materials, including graphite, graphene, carbon nanotubes (CNTs), carbon fibers (CF), and carbon black (CB); − magnetic materials, such as magnetic metal, ferrite (Fe 3 O 4 ), and carbonyl iron; − intrinsic conductive polymers such as polyaniline (PANI), polypyrrole (PPy), and polyacetylene − have been proved to be dominant materials for electromagnetic wave absorption.…”

Electromagnetic interference (EMI) -shielding and microwave-absorbing materials are of great significance in the fields of microelectronics and telecommunication to achieve electromagnetic protection and compatibility. However, it still remains a challenge to design and fabricate materials integrating both microwave absorbing and shielding properties. In this study, we prepared fluffy and porous EMI shielding materials via facile vapor deposition of pyrrole (Py) on commercial polyamide fibrous mats (FMs). The uniform polypyrrole (PPy) coating on the fiber surface endows the FM with a favorable three-dimensional (3D) conductive network. By the combination of a highly porous microstructure, the fabricated polyamide fibrous mat@polypyrrole (FM@PPy) presents excellent microwave-absorbing and EMI-shielding properties. The EMI shielding efficiency (EMI SE) of FM@PPy can reach 40 dB with a high absorption coefficient (A) of 0.8, showing extremely low reflection with “green” EMI shielding characteristics in the whole X-band (8.2–12.4 GHz). Meanwhile, the reflection loss (RL) of FM@PPy is less than −10 dB in the X-band. Moreover, FM@PPy also exhibits favorable stability and reliability as a wearable sensor. The FM@PPy demonstrates promising potential for “green” EMI shielding, broadband microwaves absorbing and highly stable intelligent sensor.
