Conventional metal electromagnetic interference (EMI) shielding cans suffer from low conformability, thickness‑performance trade‑offs, and incompatibility with advanced packaging processes. MXene nanosheets demonstrate significant potential for EMI shielding; however, they suffer from low environmental stability and bottlenecks related to film thickness. In 2025, Kang et al. published a work in Nature that overcomes thickness limitation through an embedded-MXene-in-metal shielding non-porous ultrathin structure, achieving remarkable shielding effectiveness of 70 dB and 80 dB at respective thickness of 1 μm and 1.9 μm in the X-band. The work resolves the longstanding thickness-performance dilemma in EMI shielding and provides conformal protection for USB 3.0 flash drives and flexible Schottky diodes.

MXene-coated textiles (CFs) demonstrate exceptional conductivity, electromagnetic interference shielding, and thermoregulatory performance, which have become prominent in multifunctional wearable technologies. However, inadequate textile-wettability, shielding-induced secondary pollution, and limited thermoregulation still impede their further multifunctional personal protection under extreme temperatures. Herein, we developed an electroactive hydrogel ink by combining MXene with polyvinylidene fluoride (PVDF) polymeric matrix, and then impregnated it onto the CFs to construct MXene-PVDF-CF (MX-PV-CF). The self-assembled PVDF layer modulates the MXene surface work function by forming a core–shell nanostructure, significantly improving its electro-thermal-magnetic properties. This PVDF-induced low work-function endows MX-PV-CF with remarkable multifunctionalities: 26 dB absorption-dominant electromagnetic radiation protection, high electro-thermal conversion, and a low mid-infrared emissivity (0.65). Mechanistically, the phase transitions of PVDF facilitate efficient heat dissipation, contributing to superior infrared-thermal shielding. Consequently, MX-PV-CF provides excellent extreme temperature protection, maintaining a human-comfortable temperature (10–40 °C) in extremely cold and hot environments. This work enables scalable wearable protection based on MXene-work-function-engineering under extreme temperatures, advancing intelligent protective material technology.

The traditional von Neumann computing architecture has relatively-low information processing speed and high power consumption, making it difficult to meet the computing needs of artificial intelligence (AI). Neuromorphic computing systems, with massively parallel computing capability and low power consumption, have been considered as an ideal option for data storage and AI computing in the future. Memristor, as the fourth basic electronic component besides resistance, capacitance and inductance, is one of the most competitive candidates for neuromorphic computing systems benefiting from the simple structure, continuously adjustable conductivity state, ultra-low power consumption, high switching speed and compatibility with existing CMOS technology. The memristors with applying MXene-based hybrids have attracted significant attention in recent years. Here, we introduce the latest progress in the synthesis of MXene-based hybrids and summarize their potential applications in memristor devices and neuromorphological intelligence. We explore the development trend of memristors constructed by combining MXenes with other functional materials and emphatically discuss the potential mechanism of MXenes-based memristor devices. Finally, the future prospects and directions of MXene-based memristors are briefly described.

Perovskite solar cells (Pero-SCs) exhibited a bright future for the next generation of photovoltaic technology because of their high power conversion efficiency (PCE), low cost, and simple solution process. The certified laboratory-scale PCE has reached 25.7% referred to small scale (< 0.1 cm²) of Pero-SCs. However, with the increase of the area to module scale, the PCE drops dramatically mainly due to the inadequate regulation of growing large-area perovskite films. Therefore, there is a dire need to produce high-quality perovskite films for large-area photovoltaic modules. Herein, we summarize the recent advances in perovskite photovoltaic modules (PPMs) with particular attention paid to the coating methods, as well as the growth regulation of the high-quality and large-area perovskite films. Furthermore, this study encompasses future development directions and prospects for PPMs.
