“…EM radiation with high energy can penetrate the human body, raising internal temperatures and causing damage to tissues and various health conditions, including the development of tumors and infertility, among other issues. These electromagnetic disturbances can originate either naturally or from artificial origins, encompassing sources such as the sun, earth’s magnetic field, radio transmissions, communication devices, or even vehicular traffic, and can result in operational malfunctions and device failure. − …”

The increasing demand for biodegradable and environmentally friendly materials is shifting the focus from traditional polymer composites to biocomposites in various applications, especially in electromagnetic shielding. Effective utilization of biopolymers demands improved properties and can be achieved to a certain extent by functionalization. Biopolymers such as cellulose, polylactic acid, and starch are some of the potential candidates for mitigating electromagnetic pollution in nextgeneration electronic devices because of their high aspect ratio, flexibility, light weight, high mechanical strength, thermal stability, and tunable microwave absorption to the electromagnetic interference (EMI) shielding composites. This Review provides an overview of the current advancements in EMI shielding materials and outlines recent research on EMI shielding composites that utilize various biodegradable polymer structures.

“…Traditional metal EMI shielding materials, suffering from poor corrosive resistance, relatively high weight, and untunable EMI shielding effect, take the reflection as the main shielding mechanism. Therefore, the electromagnetic waves are reflected to the devices, affecting the circuits seriously 6,7 . Comparing with metal EMI shielding materials, electrically conductive polymer composites (CPCs) containing electric fillers, providing good processibility, tunable effectivity, corrosive resistance, and low density, is getting more and more favored by researchers 2,7–9 …”

High performance electromagnetic (EM) interference shielding composites are of high demand due to increasing EM wave radiation pollution. In this work, GO/NiNCs/PMMA microcellular foams with different GO/NiNCs gradient and 3D conductive filler framework were fabricated by thermal reduction and supercritical CO 2 foaming process. With the crosslink of 1D NiNCs and 2D GO sheets, GO/NiNCs framework with electrical conductivity varied from 1.15 Â 10 À4 to highest 1.09 Â 10 À1 S/m is fabricated, exhibiting absorptiondominated electromagnetic interference shieling effectiveness (EMI SE) of 53.62 dB and specific EMI SE of 48.44 dB g À1 cm 3 in X-band. The density of GO/NiNCs/PMMA microcellular foams achieved lowest value of 0.623 g/cm 3 . Moreover, the foams showed excellent thermal conductivity and compressive strength of 178.76 MPa, indicating excellent application potential in aerospace and electronic field. The thermoplastic polymer matrix also indicates great potential in recycle of the foam material.
