“…Gyroid, as a kind of TPMS structure, has a good light absorption performance in itself, and combined with this microconfiguration, it shows a better effect. [ 40 ] On the one hand, graphene attachment increases the surface roughness, thus increasing the surface area of sunlight absorption. On the other hand, the porous morphology of microscopic folds also absorbs more incoming light, leading to better light absorption capacity.…”

Solar interfacial evaporation is a promising method for solving the global shortage of fresh water. While 2D evaporators can efficiently localize solar‐converted heat at the thin layer of the water–air interface, 3D solar evaporators can maximize energy reutilization while maintaining effective mass transport ability, few studies are conducted to explore the effect of gradient porosity on evaporation performance. In this study, a multifield assisted strategy based on a gradient 3D structure with high tortuosity is proposed, which creates a thermal field environment for efficient evaporation through high absorption of sunlight and excellent photothermal conversion and uses the gradient structure to optimize the internal pressure field to enhance water evaporation and transport. This hierarchically nanostructured solar absorber, with porosity inhomogeneity‐induced pressure gradient and optimized temperature management, is a valuable design idea for manufacturing a more efficient 3D solar evaporator in the field of seawater desalination. Owing to the understanding of optimizing the dimension by various simulation parameters, the evaporation efficiencies of such structures are found to be 165.7%, suppressing the most evaporator. Moreover, it can provide new ideas and references for the fields of mass transfer and thermal management.

“…Simultaneously, Equation 8shows that the matching thickness of the material required to achieve the optimum EMW absorption performance decreases with an increase in the dielectric constant at the same frequency, which reveals the reason for the thin material thickness of the material designed in this work. Secondly, the extensive specific surface area of the Gyroid structure facilitates multi-level reflection of electromagnetic waves on the surface of the material, which promotes the absorption of electromagnetic wave energy through the multiple scattering paths [23,38,48,75]. Moreover, on the microscopic scale, effective electromagnetic wave attenuation is achieved through interfacial polarization induced by the three-dimensional interface and dipole polarization formed by the J u s t A c c e p t e d reaction-formed mullite phase [28,76].…”

“…This technology has been initially applied in the production of macro-EM devices. [116][117][118][119][120][121][122][123] Thermoplastics such as PLA, ABS, and PVA, as well as photosensitive resins, have been used to build 3D absorbers through FDM, SLA, and DLP methods. SLS printing was also utilized to build a honeycomb structural absorber via a high-power laser beam.…”

Microwave absorption materials (MAMs) were originally developed for military purposes, but have since evolved into versatile materials with promising applications in modern technologies, including household use. Despite significant progress in bench‐side research over the past decade, MAMs remain limited in their scope and have yet to be widely adopted. This review explores the history of MAMs from first‐generation coatings to second‐generation functional absorbers, identifies bottlenecks hindering their maturation. It also presents potential solutions such as exploring broader spatial scales, advanced characterization, introducing liquid media, utilizing novel toolbox (machine learning), and proximity of lab to end‐user. Additionally, it meticulously presents compelling applications of MAMs in medicine, mechanics, energy, optics, and sensing, which go beyond absorption efficiency, along with their current development status and prospects. This interdisciplinary research direction differs from previous research which primarily focused on meeting traditional requirements (i. e., thin, lightweight, wide, and strong), and can be defined as the next generation of smart absorbers. Ultimately, the effective utilization of ubiquitous electromagnetic waves, aided by third‐generation MAMs, should be better aligned with future expectations.This article is protected by copyright.
