“…The first two methods have significant advantages, including easy operation, good reliability, and excellent designability in structure, and they receive much more favor than the other methods. Based on this idea, researchers have decorated graphene, carbon nanotubes (CNTs), MXene, and even metallic nanoparticles onto textile (another fiber-based material) to realize electromagnetic interference (EMI) shielding, , energy conversion/storage, strain sensing, − and communication − without sacrificing their inherent lightweight and flexibility. Recently, increasing efforts have been devoted to fabricating paper-based composites and exploring their potential in the fields of flexible electronics.…”

Paper, traditionally a two-dimensional assembly of randomly distributed cellulose fibers with a rough and porous surface, provides an ideal substrate for loading nanostructured materials. Integrating multifunctionality into papers offers exciting opportunities for flexible electronic materials, which are promising for wearable and portable device applications. Herein, a simple layer-by-layer (LBL) spray coating method was employed to alternatively deposit MXene and chitosan (CS) layers on paper substrate for producing flexible and multifunctional papers. The CS chain played a pivotal role as "bridge", linking Ti 3 C 2 T x MXene and ensuring the strict arrangement of hard MXene nanosheets with the intercalation of soft CS layers to construct a typical brick-and-mortar structure, a result of the electrostatic adsorption and strong hydrogen bonding interactions between these components. The electrically conductive nature of MXene coupled with this highly ordered structure endowed the nacre-mimetic-coated paper (MCP) with a high electrical conductivity of 1.09 S cm −1 , positioning it as an efficient heater capable of reachinga saturated temperature of 120 °C at 9 V driving voltage and 70 °C under a solar irradiation of 3.0 W/cm 2 . Additionally, the MCP served as a flexible sensor to accurately monitor both large-and small-scale human motions in real time. This work offers profound insights into the fabrication and functions of paper-based flexible electronic materials, and paper-based composites may become the next generation of functional materials used in electronic device fields.

With the widespread application of highly integrated electronic devices, the urgent development of multifunctional polymer‐based composite materials with high electromagnetic interference shielding effectiveness (EMI SE) and thermal conductivity capabilities is critically essential. Herein, a graphene/carbon felt/polyimide (GCF/PI) composite is prepared through constructing 3D van der Waals heterostructure by heating carbon felt and graphene at high temperature. The GCF‐3/PI composite exhibits the highest through‐plane thermal conductivity with 1.31 W·m−1·K−1, when the content of carbon felt and graphene is 14.1 and 1.4 wt.%, respectively. The GCF‐3/PI composite material achieves a thermal conductivity that surpasses pure PI by 4.9 times. Additionally, GCF‐3/PI composite shows an outstanding EMI SE of 69.4 dB compared to 33.1 dB for CF/PI at 12 GHz. The 3D van der Waals heterostructure constructed by carbon felt and graphene sheets is conducive to the formation of continuous networks, providing fast channels for the transmission of phonons and carriers. This study provides a guidance on the impact of 3D van der Waals heterostructures on the thermal and EMI shielding properties of composites.

Flexible pressure sensors (FPS) are crucial for emerging applications like wearable electronics, human activity monitoring, and soft robotics. This study reports a scalable and cost‐effective approach to fabricate high‐performance piezoresistive FPS based on polyurethane‐silicone rubber (PU‐SR) nanocomposites. The synergistic integration of nitrogen‐doped bamboo‐shaped carbon nanotubes (N‐BCNT) and carbon black (CB) nanofillers within the PU‐SR matrix was achieved via a novel dip‐coating and impregnation method. This technique enabled uniform nanofiller dispersion, enhancing electrical conductivity and mechanical stability. Comprehensive characterization using x‐ray photoelectron spectroscopy (XPS), zeta potential, high‐resolution transmission electron microscopy (HRTEM), and micro‐computed tomography (Micro‐CT) elucidated the structural features and morphological aspects. The optimized N‐BCNT:CB/PU‐SR nanocomposite exhibited exceptional piezoresistive performance, with a sensitivity of 0.4 kPa−1 in the 0–120 kPa range and 0.07 kPa−1 in the 180–1000 kPa range, along with remarkable durability over cyclic loading. When deployed as an electronic skin (e‐skin), the sensor accurately detected various human motions, including finger, wrist, elbow, and knee movements, as well as twisting and stretching actions. This work shows a promising route towards fabricating cost‐effective, flexible, and high‐performance pressure sensors with significant implications for wearable technologies and soft robotics.Highlights Hybrid Nanocomposite sensors achieve high sensitivity over a broad pressure range. N‐CNTs and CB enhance piezoresistivity and durability in PU‐SR nanocomposites. Flexible sensors detect multi‐joint human motions accurately. Alternative dip‐coating technique ensures uniform nanofiller distribution. Cost‐efficient sensors design suitable for wearable e‐skin applications.
