Smart and multifunctional fiber reinforced polymer (FRP) composites with energy storage, sensing, and heating capabilities have gained significant interest for automotive, civil, and aerospace applications. However, achieving smart and multifunctional capabilities in an FRP composite while maintaining desired mechanical properties remains challenging. Here, a novel approach for layer‐by‐layer (LBL) deposition of 2D material (graphene and molybdenum disulfide, MoS2)‐based heterostructure onto glass fiber fabric using a highly scalable manufacturing technique at a remarkable speed of ≈150 m min−1 is reported. This process enables the creation of smart textiles with integrated energy storage, sensing, and heating functionalities. This methodology combines gel‐based electrolyte with a vacuum resin infusion technique, resulting in an efficient and stable smart FRP composite with an areal capacitance of up to ≈182 µF cm−2 at 10 mV s−1. The composite exhibits exceptional cyclic stability, maintaining ≈90% capacitance after 1000 cycles. Moreover, the smart composite demonstrates joule heating, reaching from ≈24 to ≈27 °C within 120 s at 25 V. Additionally, the smart composite displays strain sensitivity by altering electrical resistance with longitudinal strain, enabling structural health monitoring. These findings highlight the potential of smart composites for multifunctional applications and provide an important step toward realizing their actual real‐world applications.

“…MoS 2 , as a typical two-dimensional (2D) nanomaterial, has excellent conductivity, chemical stability, photothermal conversion rate, biocompatibility, and mechanical properties, so it has broad prospects for applications in fields such as nanoelectronics, chemical sensors, electrocatalysis, high-density batteries, lubricants, and biomedicine. − MoS 2 had also been reported to inhibit ice crystal size effectively and can quickly rewarm, making it suitable for cell cryopreservation. , Zhao et al explored the photothermal properties of MoS 2 NSs and their inhibitory effects on ice nucleation and crystal growth during the recovery process. Further, using near-infrared laser induction, HUVEC cells were rapidly resuscitated with a high survival rate, achieving effective cryopreservation of cells .…”

With the booming development of nanotechnology, an increasing number of nanomaterials and engineering strategies are being used to explore the effective inhibition of ice crystals, thereby reducing ice damage to biological samples and improving the efficiency of cryopreservation. However, the ice-inhibiting effect of nanomaterial shapes and their corresponding photothermal behavior have rarely been studied in depth in cell cryopreservation applications. Here, molybdenum disulfide (MoS2) nanomaterials with different morphologies [nanosheets (NSs), nanoflowers (FLs), and nanomicrospheres (MSs)] were controllably synthesized by a hydrothermal method to profile the influence of MoS2 morphology on ice suppression and rapid rewarming. The prepared MoS2 nanomaterials exhibited excellent capabilities for regulating the nucleation temperature and recrystallization size of ice crystals, which varied with morphology (MSs > FLs > NSs). Unique surface morphology, more functional groups on the surface that could form hydrogen bonds with ice/water molecules, and the adsorption-inhibition mechanism contributed to the excellent ice regulation performance. Surprisingly, the photothermal effect of MoS2 MSs was also the best as the temperature could sharply rise from 24 to 82 °C under 808 nm laser irradiation for 1 min. Finally, using MoS2 MSs as a cryoprotectant (CPA) to cryopreserve A549 cells, a cell survival rate of 85.3% was still achieved even when MoS2 MSs replaced 90% of dimethyl sulfoxide in the CPA solution. Our work is the first to correlate the shape variations of nanomaterials with their regulation of ice crystal behavior during the freezing-thawing process and photothermal properties, synergistically improving the efficiency of cell cryopreservation. This study provides guidance for the practical design of nanomaterials for collaborative deicing.

“…The electrochemical characteristics of the supercapacitor mainly depend on the properties of electrode materials. Although high-performance supercapacitor materials, such as graphene, carbon nanomaterials, metal oxides and conductive polymers, have been greatly developed [6][7][8][9], the low sustainability and high cost limit their practical applications. Therefore, the development of low-cost carbon sources to prepare superb electrodes becomes an important topic in this field.…”

The optimization of supercapacitive properties in carbon materials derived from cheap and sustainable wood scraps exhibits great application potential. Herein, in support of interfacial groups, polyaniline nanospheres were in situ constructed in the internal pore structure of wood scraps; further, the B and N elements were imported by carbonized and hydrothermal methods. The doped B regulated the species of N doping to improve the electrical conductivity of carbonized wood scraps, and it endowed a certain pseudo-capacitance. Coupled with the fine double-layer capacitance from the hierarchical structures constructed by carbonized nanospheres and wood scrap channels, a high specific capacitance of 406 F g−1 at 0.5 A g−1, high energy density (17.71 Wh kg−1 at 250 W kg−1) and cycle stability (93.04% capacitance retention after 10,000 cycles) were performed simultaneously. This study provided a new strategy to improve the supercapacitive performance of bio-carbon materials in terms of structure and conductance.
