Stimuli-responsive materials exhibit huge potential in sensors, actuators, and electronics; however, their further development for reinforcement, visualization, biomass-incorporation remains challenging. Herein, based on the impregnation of thermochromic microcapsule (TCM)-doped dynamic covalent vitrimers, a programmable shape-color dual-responsive wood (SRW-TC) was demonstrated with robust anisotropic structures exchangeable adaptable networks. Under mild conditions, resultant SRW-TC displays feasible shape memorability programmability, resulting from rigidity–flexibility shift induced by glass-transition temperature (34.99 °C) transesterification reaction triggered topology freezing transition (149.62 °C). Furthermore, obtained possesses satisfactory mechanical performance (tensile strength 45.70 MPa), thermal insulation (thermal conductivity 0.27 W/m K), light management, benign optical properties (transmittance 51.73% haze 99.67% at 800 nm). Importantly, incorporation compatible TCM enables to visualize memory feasibility rigidity/flexibility switching respond external stimulus through thermal-induced shape–color synchronous dual-responsiveness, which successfully demonstrates applications sensing temperature, grasping objects, encrypting/decoding icon messages, so on. The proposed facile highly effective strategy could serve as guideline developing high-performance multifunctional composite promising intelligent environmental sensing, interactivity, information dual-encryption, local precision color regulation, etc.

This paper compares different uniaxial and biaxial graded designs of auxetic reentrant honeycomb structures to enhance their mechanical properties, especially the specific energy absorption under compressive load. The lattice were 3D printed using vat photopolymerization masked-stereolithography technique from two materials – tough (OR) flexible (FR). results evaluated a material structural point view, investigating effect porosity, cell number, size, design, fracture mode. universally best energy-absorbing performance was found in biaxially structure with center-wise location highest local porosity. Depending on used resin, its capacity up 2–3 times enhanced compared reference uniform-porosity design. presented data constitutes fundamental understanding identifies practical approaches for tuning structures' regarding response. Finally, this study demonstrates potential shape versatility offered by printing other additive manufacturing techniques.

Abstract Structural materials such as ceramics, metals, and carbon fiber‐reinforced plastics (CFRP) are frequently threatened by large compressive impact forces. Energy absorption layers, i.e., polyurethane silicone foams with excellent damping properties, applied on the surfaces of different substrates to absorb energy. However, amount energy dissipation penetration resistance limited in commercial foams. Herein, a distinctive nacre‐like architecture design strategy is proposed integrating hard porous ceramic frameworks flexible buffers improve resistance. Experimental investigations reveal bioinspired designs exhibit optimized hardness, strength, modulus compared that polyurethane. Due multiscale mechanisms, resulting normalized absorbed (≈8.557 MJ m −3 ) ≈20 times higher than under 50% quasi‐static compression. The composites provide superior protection for structural (CFRP, glass, steel), surpassing films loadings. It shown CFRP coated designed can withstand more ten loadings (in 10 J) without obvious damage, which otherwise delaminates after single impact. This biomimetic holds potential offer valuable insights development lightweight, energy‐absorbent, impact‐resistant materials.

Ceramic materials, while strong, often lack flexibility and energy absorption. Inspired by tough natural structures like nacre, toughening strategies have shown significant potential in ceramic materials. This study investigates the static cyclic flexural properties (i.e., absorption, stiffness, strength) of bioinspired ceramic-polymer composites, particularly concerning influence macro micro patterns. Using a subtractive manufacturing platform enabled ultra-short pulsed picosecond lasers, we engrave range patterns onto alumina tiles, mimicking armor designs. The composites are then fabricated stacking laser-engraved tiles with an interlayer Surlyn®, commercial monomer. results demonstrate that static/cyclic performance mechanisms closely linked to lasered surface sequence. Specific architectures sequences led significantly increased absorption (up 85%) through crack deflection plastic deformation soft phase. Micro patterns, on other hand, improved ceramic's strength 140%) influencing how materials interact at interface. research not only advances our understanding but also paves way for new generation superior properties, targeting applications defense (aerospace vehicle armor) personal protective equipment (PPE).
