From an environmentally sustainable perspective, soybean meal (SM) adhesive presents ideal alternative to petrochemical-based adhesives. Generally, strength and toughness are mutually exclusive for adhesive. Hence, the creation of protein-based adhesives with high water-resistant bonding, remarkable toughness, multifunctionality remains a notable challenge. This study reports dual hyperbranched siloxane nanocluster cross-linking strategy creating SM-based superior performance. In detail, synthesized epoxy (ESN) phenylboronic acid (BPA@SN) were introduced into SM matrix establish targeted network between groups protein chains as well polysaccharides. Meanwhile, flexible Si–O segments within facilitated energy dissipation, significantly boosting toughness. After modification, SM/ESN/BPA@SN-1 demonstrated outstanding dry bonding (2.04 ± 0.18 MPa), (1.12 0.06 (18.5 4.02 kJ/m3). Moreover, exhibited distinctly improved resistance mold, thermal stability, flame retardancy. Therefore, this new using functional nanoclusters design strong, tough, multifunctional green wood-based biomass provides ideas achieving development.

Liquid Metal‐MXene‐Based Hierarchical Aerogel with Radar‐Infrared Compatible Camouflage

Advanced Functional Materials, Год журнала: 2023, Номер 34(10)

Опубликована: Ноя. 21, 2023

Abstract As military power advances in the realm of information warfare, stealth technology has become a critical area research for its effectiveness to evade detection. However, achieving high performance compatible across different functional mode bands remains significant challenge. In this study, drawing inspiration from plant bionics, concepts directional freezing process are applied develop liquid metal‐MXene‐based hierarchical aerogel with radar‐infrared camouflage. With density only 4.4 mg cm −3 , maximum reflection loss can reach −73.2 dB, and absorption bandwidth be adjusted up 7 GHz. Following thermal camouflage durability test, sample successfully lowers target's temperature 400 ≈160 °C. Remarkably, stable even after 180 days exposure. Additionally, material's ease machining enables shape‐shifting capabilities, allowing objects transform resemble harmless items, thereby blending seamlessly their surroundings. This breakthrough compatibility signifies substantial leap forward multifunctional development. It not introduces innovative concepts, but also provides technical support, catalyzing further advancement field.

A mini‐review of ultra‐low dielectric constant intrinsic epoxy resins: Mechanism, preparation and application

Polymers for Advanced Technologies, Год журнала: 2023, Номер 35(1)

Опубликована: Ноя. 23, 2023

Abstract Epoxy resins are widely utilized in electronics, electrical components, and communication equipment for polymer‐based wave‐transparent composites. However, the dielectric constant ( ε ) loss (tan δ of common epoxy relatively high 3.8–4.2; tan 0.018–0.025), corresponding impact resistance is poor. Thus, it cannot meet requirements advanced microelectronic materials. And prepared by filling inorganic fillers difficult to combine low with good machining performance. The intrinsic can be decreased synthesis monomers curing agents optimization final network. Meanwhile, use some special processing methods, such as electrospinning technology, also conducive reducing values epoxy‐cured resins. factors affecting properties resins, methods decrease value reviewed this article. Then, design, research progress ultra‐low investigated relevant academic results. Finally, development trends application prospects discussed.

Abstract Superhydrophobic materials are attractive for industrial development but plagued by poor mechanical stability. Herein, a superdurable full‐life superhydrophobic composite block is designed and fabricated embedding near‐zero contractive silica aerogel into rigid iron‐nickel foam structured similarly to regular dodecahedron. The synergistic protection afforded these ensures superrobust stability the block, which features high compressive strength of up ≈7.4 MPa, ultralow Taber abrasion down ≈0.567 mm after withstanding 50 000 cycles, highly efficient water harvesting capability ≈3114.3 mg min −1 cm −2 at supercooling degree 40 K. This robust material system provides novel strategy design capable extreme conditions, including temperature, humidity, pressure, abrasion.
