Abstract With the advent of 5G/6G for radar and space communication systems, various millimeter‐wave (MMW) components are rapidly innovated multi‐functional, higher integrated miniaturized solutions across diverse industries applications. Polymer composites‐based additive manufacturing (AM), an advanced technique, can manufacture MMW with high fabrication resolution, intricate structural design, adjustable dielectric properties, functionally gradient distribution characteristics. This paper outlines state‐of‐the‐art polymer composite components, their techniques. An “material‐structure‐manufacturing‐performance” design conceptual framework is discussed in terms material structure process design. Moreover, multi‐functional structures focus on electromagnetic wave absorption interference (EMI) shielding functions. novel applications enabled by AM radar/sensing, communication, enclosure, miscellaneous discussed. Furthermore, future perspectives current challenges identified to provide new insights into 3D‐printed products, exploring possibilities next‐generation technology. Highlights The reviewed. concept introduced. radar, Future addressed.

Current progress and frontiers in three-dimensional macroporous carbon-based aerogels for electromagnetic wave absorption: A review

Nanoscale, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 1, 2024

In the present era of rapid development in electronic information technology, electromagnetic (EM) pollution is increasingly receiving widespread concerns due to its potential threats devices and human health. EM wave absorbing materials (EWAMs) play an important role preventing exposure waves because they can attenuate incident through sustainable energy dissipation. Among numerous EWAMs developed recent years, three-dimensional (3D) macroporous carbon-based aerogels have been considered one most promising candidates as high-performance not only their flexible component options beneficial synergies between different components but also for open skeletons, which provide a unique structural contribution accelerating consumption waves. this review, we focus on current progress 3D toward absorption highlight strategies preparation, including biomass transformation, template method, hydrothermal/solvothermal self-assembly, polymer foaming, metal-organic frameworks (MOFs) topological transformation. Moreover, discuss analyze effects composition, optimization engineering performances. After comprehensive evaluation performance aerogels, further propose some challenges perspectives envision broad application prospects future.
