“…Compared to pure PA12, 0.5 wt.% showed less fracture toughness, 1.0 wt.% showed almost similar fracture toughness, and 2.0 wt.% revealed higher fracture toughness. Additionally, there is an investigation on ABS/CB composites, which also underwent electrical conductivity testing, and it was proved that although the rise of CB percentage increases the electrical conductivity (which agrees with the study herein) the mechanical properties are reduced (which does not match the results of this study) [60].…”

High-density polyethylene polymer (HDPE) and carbon black (CB) were utilized to create HDPE/CB composites with different filler concentrations (0.0, 2.0, 4.0, 6.0, 8.0, 10.0, 16.0, 20.0, and 24.0 wt.%). The composites were extruded into filaments, which were then utilized to fabricate 3D-printed specimens with the material extrusion (MEX) method, suitable for a variety of standard mechanical tests. The electrical conductivity was investigated. Furthermore, thermogravimetric analysis and differential scanning calorimetry were carried out for all the HDPE/CB composites and pure HDPE. Scanning electron microscopy in different magnifications was performed on the specimens’ fracture and side surfaces to investigate the morphological characteristics. Rheological tests and Raman spectroscopy were also performed. Eleven different tests in total were performed to fully characterize the composites and reveal connections between their various properties. HDPE/CB 20.0 wt.% showed the greatest reinforcement results in relation to pure HDPE. Such composites are novel in the MEX 3D printing method. The addition of the CB filler greatly enhanced the performance of the popular HDPE polymer, expanding its applications.

“…Polymeric composites or reinforced polymeric configurations offer an exceptional platform for creating 3D-printed EMI shields with custom geometries and tunable porosities. To this end, PLA, [161] acrylonitrile butadiene styrene (ABS) plastic, [162] and epoxies [163] are among the most studied polymers used for the FDM 3D-printing of EMI shields. Generally, because pristine polymers do not have effective conductivity to exhibit proper EMI shielding performance, highly conductive/magnetic fillers or lossy materials (e.g., MXene, [164] graphene, [159] and CNT [165] ) can be mixed with the polymer matrices to enhance their shielding performance.…”

Modern human civilization deeply relies on the rapid advancement of cutting‐edge electronic systems that have revolutionized communication, education, aviation, and entertainment. However, the electromagnetic interference (EMI) generated by digital systems poses a significant threat to our society, potentially leading to a future crisis. While numerous efforts have been made to develop nanotechnological shielding systems to mitigate the detrimental effects of EMI, there has been limited focus on creating absorption‐dominant shielding solutions. Achieving absorption‐dominant EMI shields requires careful structural design engineering, starting from the smallest components and considering the most effective electromagnetic wave (EMW) attenuating factors. This review offers a comprehensive overview of shielding structures, emphasizing the critical elements of absorption‐dominant shielding design, shielding mechanisms, limitations of both traditional and nanotechnological EMI shields, and common misconceptions about the foundational principles of EMI shielding science. This systematic review serves as a scientific guide for designing shielding structures that prioritize absorption, highlighting an often‐overlooked aspect of shielding science.This article is protected by copyright.

Emerging technology and modernization have become a worldwide threat to human life in all aspects. Worldwide, all countries are in the race to develop the most advanced electronic devices and gadgets as they reflect the country's superiority and economic development. Specialists have forecasted that during and after the pandemic, the addiction toward modern gadgets have increased by 40% among the people irrespective of age. A few researchers have reported that the world economy is dependent on and dominated by countries manufacturing semiconductors, mobiles, electronic chips, and so on. People started sensing that modern devices are like a boon, as their lives seem to be more connected and comfortable with all their needs and wants being fulfilled at their doorsteps. But this boon is slowly whirling as a severe threat to human lives. Due to this rapid usage of electronic devices, electromagnetic interference (EMI) is drastically growing, which is considered a global warning issue for commercial and biological systems. So advanced countries have decided to make EMI shielding a compulsory entity to be implemented in all advanced electronic devices. Though traditional materials like metals and carbon allotropes have excellent shielding properties, they cannot cope with today's mass production of modern devices. Thus, researchers had to find a suitable substitute material that should possess properties such as sustainability and biocompatibility to overcome problems faced by the conventional materials. Thus, polymers have come into the world of EMI shielding applications. Polyvinylidene fluoride (PVDF), a non‐conductive polymer from the family of Fluorocarbons, is creating history in the field of EMI shielding applications. PVDF astonished researchers with its versatile features, such as light weight, flexibility, and easy processibility with excellent dielectric and piezoelectric properties. Though they are poor in electrically conductive properties, incorporating metals, carbon allotropes, and metal oxides as fillers make them superior to the existing conventional materials. Thus, the main objective of this review article is to highlight the uniqueness of PVDF as an advanced polymer for EMI shielding applications. It has been noted that PVDF is more suitable for EMI shielding in X, K, and Ku band frequencies. But overall, we noticed that the performance of PVDF has a great impact by incorporating a combination of metal and carbon allotrope enhances the shielding effectiveness up to 65 dB in the Ku‐band (Kurz‐under) frequency band range of (12–18 GHz).
