Abstract The morphological distribution of absorbent in composites is equally important with absorbents for the overall electromagnetic properties, but it often ignored. Herein, a comprehensive consideration including component regulation, layered arrangement structure, and gradient concentration was used to optimize impedance matching enhance loss. On microscale, incorporation magnetic Ni nanoparticles into MXene nanosheets (Ni@MXene) endows suitable intrinsic permittivity permeability. macroscale, Ni@MXene increases effective interaction area waves, inducing multiple reflection/scattering effects. this basis, according analysis absorption, reflection, transmission (A–R–T) power coefficients composites, constructed realize at low-concentration surface layer, loss middle interlayer microwave reflection high-concentration bottom layer. Consequently, composite (LG5-10–15) achieves complete absorption coverage X-band thickness 2.00–2.20 mm RL min −68.67 dB 9.85 GHz 2.05 mm, which 199.0%, 12.6%, 50.6% higher than non-layered, descending respectively. Therefore, work confirms importance structure improving performance broadens design high-performance materials.

Abstract Renewable 2,5-furandicarboxylic acid-based polyesters are one of the most promising materials for achieving plastic replacement in age energy and environmental crisis. However, their properties still cannot compete with those petrochemical-based plastics, owing to insufficient molecular and/or microstructure designs. Herein, we utilize Ti 3 C 2 T x -based MXene nanosheets decorating carbon nanotube (CNT) obtaining structurally stable highly dispersed dendritic hetero-structured MXene@CNT, that can act as multi-roles, i.e., polycondensation catalyst, crystal nucleator, interface enhancer polyester. The bio-based MXene@CNT/polybutylene furandicarboxylate (PBF) (denoted MCP) nanocomposites synthesized by strategy “in situ catalytic polymerization hot-pressing”. Benefiting from multi-scale interactions (i.e., covalent bonds, hydrogen physical interlocks) hybrid structure, MCP presents exceptional mechanical strength (≈101 MPa), stiffness (≈3.1 GPa), toughness (≈130 MJ m −3 ), barrier (e.g., O 0.0187 barrer, CO 0.0264 H 1.57 × 10 −14 g cm −2 s Pa) higher than reported engineering plastics. Moreover, it also displays satisfactory multifunctionality high reprocessability (90% retention after 5 recycling), UV resistance (blocking 85% UVA rays), solvent-resistant properties. As a state-of-art high-performance multifunctional material, novel nanocomposite offers more sustainable alternative plastics packaging material fields. More importantly, our catalysis-interfacial strengthening integration opens door designing constructing polyester future.

Abstract Currently, numerous biomimetic robots inspired by natural biological systems have been developed. However, creating soft with versatile locomotion modes remains a significant challenge. Snakes, as invertebrate reptiles, exhibit diverse and powerful abilities, including prey constriction, sidewinding, accordion locomotion, winding climbing, making them focus of robotics research. In this study, we present snake-inspired robot an initial coiling structure, fabricated using MXene-cellulose nanofiber ink printed on pre-expanded polyethylene film through direct writing technology. The controllable fabrication structure (ICSBot) has achieved theoretical calculations finite element analysis to predict analyze the ICSBot, programmable ICSBot designed fabricated. This functions gripper capable grasping objects complex shapes under near infrared light stimulation. Additionally, it demonstrates multi-modal crawling in various environments, confined spaces, unstructured terrains, both inside outside tubes. These results offer novel strategy for designing fabricating coiling-structured highlight their potential applications smart multifunctional robotics.
