Graphene has been one of the most widely explored two-dimensional (2D) assemblies due to its outstanding mechanical, electrical, and thermal properties resulting from unique characteristics high anisotropy strong carbon-carbon bonds. Aerogels, characterized by their ultralow density ultrahigh specific surface area, stand out as leading porous materials. Therefore, integration graphene aerogels would boost development multifunctional Among various methods for fabrication aerogels, ice-templating received significant interest ecofriendly nature a physical process, broad applicability across material systems, proficiency in constructing abundant structures multifunctionalities. Consequently, become prevalent technique efficient assembly nanosheets into with inherited graphene, multifunctionality derived diverse constituents, well-controlled architecture. In this review, we systematically summarize progress ice-templated graphene-based aerogels. Initially, introduce process these elaborating each step precursor preparation freezing, drying, post-treatment. Subsequently, demonstrate applications macroarchitectures microstructures. Finally, review concludes straightforward summary, highlighting challenges opportunities associated This systematic aims offer new insights design innovative multiscale architecture multifunctionalities, which are crucial variety engineering applications.

Abstract The aerogel materials stacked with nanomaterials usually have good thermal insulation and electromagnetic wave (EMW) absorption properties due to their porous properties. However, consecutive mechanical loading cycles under extreme temperature environments cause irreversible structural damage. Furthermore, there is an inherent contradiction between the characteristics of multiple interfaces anti‐fatigue performance. In this study, polyimide (PI) fibers are dispersed in graphene aerogel, composite (G‐PI@F 20 /CNT x ) can be formed by situ welding. hierarchical structure endows excellent superelasticity, insulation, EMW endures 90% strain compression over a range −196 160 °C, deformation loss remaining below 5%. This hinders phonon conduction, resulting low conductivity (0.0313 W m −1 K ). thickness 4.1 mm achieves effective bandwidth (EAB) 12.48 GHz. By increasing 20.3 mm, ultra‐broadband 15.24 GHz optimal reflection (RL min −43.49 dB attained. These findings provide crucial insights into design multifunctional absorbing offer general strategy for synthesizing superelastic aerogels.

Aerogels have attracted great attention in the academic and industrial fields due to their intrinsic low density, high porosity, specific surface area. As an ideal nanobuilding block for advanced aerogels, research community has shown a strong interest aramid nanofiber (ANF) aerogel materials applications frontier fields. However, there is lack of comprehensive review basic development practical pure ANF aerogels regarding these latest achievements past decade. This aims fill this gap by comprehensively exploring preparation, properties, application progress, challenges, prospects aerogels. We begin with summary rheological principles dispersions, different preparation strategies, drying methods Then, unique properties various morphologies outstanding advantages based on are critically reviewed. Besides, progress multifunctional flexible thermal insulation, environmental protection, energy storage, other summarized. Finally, we explore main challenges give insights further promotion from lab-scale industry-scale.
