The unique material structure and pronounced anisotropy of wood bestow it with an array remarkable properties, creating opportunities for designing functional materials. This study investigates the application wood's anisotropic in temperature‐controlled intelligent electric heating materials by preparing wood‐based graphene composites (GNPs@EW). Graphene nanosheets (GNPs) are incorporated into a birch matrix (EW) to enhance electrical thermal conductivity insulating wood. integration is confirmed through Fourier transform infrared spectrometer (FTIR) X‐ray diffractometer (XRD) analysis. optimal composite (GNPs@EW 1 ) prepared graphene‐to‐anhydrous ethanol mass ratio 1:1. results demonstrate influence on composites, revealing superior performance axial direction compared tangential direction. resistivity GNPs@EW along decreases 2.1–2.9 times relative direction, temperature rise after energization at 6 V 22–29 °C higher Furthermore, exhibits stability, enhanced mechanical uniformity, establishing these properties as foundation development innovative smart applications.

Fiber-shaped electrical heaters with high flexibility and excellent adaptability make an ideal candidate for the application of wearable electronics but still suffer from low strength poor durability. Herein, all-in-one Joule-heating fiber capable outstanding mechanical properties, good heating efficiency, long-term stability is reported by using polymer-assisted metal deposition to firmly coat Cu nanoparticles on high-performance liquid crystal polymer (LCP) fibers. Taking advantage LCP, resultant fibers exhibit a satisfying temperature threshold (up 200 °C) immense (2.94 GPa). By virtue dense continuous film, these show resistance (5.51 Ω/cm) ultrafast response rate (12.6 °C·s−1) at supplied voltages (0.5–3.5 V). Benefiting levodopa/polyethyleneimine interface design, such maintain nearly constant after repeatable bending, folding, even washing (50 cycles). Based above-mentioned merits, patch function knitted as-made offer therapeutic benefits human body joints. This work demonstrates prospective potential enriching challenging applications fiber-shaped systems.

A flexible electrode is a key component of electrothermal film for deicing. Here, silver electrodes were fabricated via screen printing 55 wt % content polypolyphenoxy (PKHH) resin-based conductive paste on the porous graphene-skinned quartz fiber fabric without precoating layer. PKHH favorable excellent performance electrodes, such as low resistivity (1.32 × 10–5 Ω·cm), high adhesion (5B), and tolerance bending deformation. Fluorine-modified epoxy resin was introduced to electrically adhesive (ECA) improve hydrophobicity avoid corrosion/oxidation Ag during deicing process, ECA showed (2.4 10–4 Ω·cm) stable mechanical connection (15 MPa). The feasibility demonstrated.
