Abstract The combination between macroscopic structure designs and microscopic material offers tremendous possibilities for the development of advanced electromagnetic wave (EMW) absorbers. Herein, we propose a metamaterial design to address persistent challenges in this field, including narrow bandwidth, low–frequency bottlenecks, and, particularly, urgent issue robustness (i.e., oblique, polarized incidence). Our absorber features semiconductive metal-organic framework/iron 2D/2D assembly (CuHT–FCIP) with abundant crystal/crystal heterojunctions strong magneto-electric coupling networks. This achieves remarkable EMW absorption across broad range (2 40 GHz) at thickness just 9.3 mm. Notably, it maintains stable performance against oblique incidence (within 75°) polarizations (both transverse electric magnetic). Furthermore, demonstrates high specific compressive strength (201.01 MPa·cm 3 ·g −1 ) low density (0.89 g·cm −3 ). advancement holds promise developing robust absorbers superior performance.

The utilization of metal–organic frameworks (MOFs) in energy storage applications is constrained by their limited electrical conductivity and insufficient chemical robustness, posing various challenges limitations. Nevertheless, research has demonstrated that MOF structures with exceptional porosity adaptable architectures yield a wide range composites, presenting promising prospects for improving electrochemical performance devices. When combined other advanced materials, MOFs form composite overcoming these constraints exhibiting superior conductivity, activity, stability comparison to pure MOFs. This article comprehensively overviews the designed chemistry MOF-composites metal-ion batteries (MIBs) capacitors (MICs). synthesis properties composites involving MOFs, including MOF-MXene, MOF-carbon nanomaterials (CNM)/graphene/carbon, MOF-transition metal oxide (TMO), MOF/polymers, MOF-derived layered double hydroxide (LDH), as well mitigation strategies have been discussed. A brief overview electrode materials MIBs, lithium-ion (LIBs), sodium-ion (SIBs), potassium-ion (KIBs) presented. recent developments MICs, such (LICs), magnesium-ion (MGICs), zinc-ion (ZICs), (SICs), (KICs) also included. Furthermore, assessed using metrics, output voltage, capacity, cycle stability, density (ED), power (PD). comprehensive analysis conducted identify potential obstacles possible mitigations explore future possibilities. Overall, comprehension MOF-based approaches enhancing futuristic progression MOF-composite MIBs MICs elucidated.
