Abstract ：
This study develops a functionalization strategy for incorporating cellulose nanocrystals (CNCs) into unsaturated polyester resin (UPR) to simultaneously enhance its strength and toughness. Surface modification of CNCs was achieved through sequential reactions with toluene diisocyanate (TDI) and hydroxyethyl acrylate (HEA), introducing carbon double bonds(C=C) to obtain modified CNC (m-CNC). The m-CNC was subsequently compounded with UPR to fabricate composite materials. A comprehensive investigation of the composites' morphological features, mechanical performance, and thermal behavior was conducted through transmission electron microscopy (TEM), mechanical testing, dynamic mechanical analysis (DMA), and thermogravimetric analysis (TGA). Experimental results demonstrate that 0.3 wt% m-CNC incorporation markedly improves UPR's mechanical properties, with the composite exhibiting 23.55% higher tensile strength, 59.01% increased flexural strength, and 96.16% enhanced impact resistance compared to unmodified UPR. DMA characterization revealed that covalent cross-linking between m-CNC and the UPR matrix restricts polymer chain mobility, resulting in a 35.4% elevation in storage modulus. TGA data confirmed the heat resistance improvement, showing 12.8 degrees C and 9.3 degrees C increases in thermal decomposition temperatures for m-CNC/UPR composites relative to pure UPR and unmodified CNCs/UPR systems, respectively. This synergistic modification approach effectively balances structural integrity preservation of CNCs with significant enhancement of UPR's multifunctional performance, demonstrating potential applications in automotive, construction, new energy, and eco-friendly packaging industries. It emerges as a promising alternative to conventional composite materials.

Abstract ：
Glass fiber-reinforced polymer (GFRP) composites were prepared by hand lay-up using unsaturated polyester resin (UPR) matrices in which a hyperbranched polyester (HBP) synthesized via a polyethylene glycol (PEG) core route was incorporated. Glass fibers (GFs) were functionalized to create "rigid" (HEA/TDI-modified, m-GF) and "flexible" (KH570-modified, KH570-GF) interfaces. HBP-modified UPR composites exhibited enhanced tensile, flexural, and impact strengths by 62.2%, 17.5%, and 95.0%, respectively, versus unmodified counterparts. Introducing the rigid m-GF interface further amplified these improvements, achieving strength gains of 96.1% (tensile), 90.9% (flexural), and 80.4% (impact). The flexible KH570-GF interface yielded the most pronounced synergistic effect: the optimum system (KH570-GF + 5 wt% HBP) achieved a tensile strength of 336.8 MPa (a 113% increase), a flexural strength of 622.1 MPa (93.6% increase), and an impact strength of 142.2 kJ m-2 (187% increase) relative to the baseline GF/UPR composite. Dynamic mechanical analysis confirmed increased glass transition temperatures, indicating enhanced thermal stability from improved crosslinking. Scanning electron microscopy demonstrated reduced fiber-matrix debonding and suppressed crack propagation in the modified systems. The rigid interface primarily enhanced load transfer efficiency, whereas the flexible interface promoted energy absorption via interfacial slippage. These findings illustrate that independent tailoring of rigid or flexible interfaces provides distinct pathways for performance optimization, effectively overcoming the traditional strength-toughness trade-off in GFRPs and offering customizable solutions for aerospace and structural applications.

Abstract ：
Thin films with adjustable refractive indices are crucial for fabricating multi-layer antireflective coatings (ARCs). Conventional sol-gel methods typically require the incorporation of templates or modifiers to precisely control film porosity and refractive index. In this work, we propose a template-and modifier-free sol-gel method to precisely engineer the chemical-and micro-structure of silica nanoparticles (SNPs), enabling the fabrication of silica thin films with tunable refractive indices ranging from 1.15 to 1.38 using only tetraethoxysilane (TEOS), ethanol, ammonia water, and water as raw materials. By simply adjusting NH3 center dot H2O and H2O content, the hydrolysis and condensation of TEOS can be controlled to obtain SNPs with adjustable chemical-and microstructure, which enable the control of inter-particle and intra-particle porosity. It is found that at low NH3 center dot H2O content, the resulting SNPs exhibit a surface abundant in hydrophobic ethoxy groups, which effectively reduce the capillary pressure within a thin film during the drying process, thereby inhibiting the film shrinkage, increasing the porosity, and ultimately producing a hydrophobic film with a refractive index as low as 1.15. Conversely, with high NH3 center dot H2O content, the resultant SNPs have few hydrophobic ethoxy groups on their sur-face, exhibiting excellent hydrophilicity. The resultant increased capillary pressure induces significant film shrinkage during the drying process, resulting in a thin film with low porosity and high refractive index. Finally, leveraging this tunability of refractive index, we successfully fabricated a double-layer hydrophobic broadband ARC with excellent optical performance, where the thin films prepared with high and low NH3 center dot H2O contents were integrated as bottom and top layers, respectively.

Abstract ：
Poor mechanical stability of superhydrophobic coating limits its practical application. In this work, robust superhydrophobic organically modified silicate (ORMOSIL) hybrid coatings were fabricated on wood surface by a chemical-assembly engineering induced by click reaction of PMHS. The superhydrophobic ORMOSIL coating was hybridized from poly(methylhydrogen)siloxane (PMHS), tetravinyltetramethylcyclotetrasiloxane (V4), and silica nanoparticles (SNPs). The click reaction between PMHS and SNPs built a chemically bonded rough surface with very low surface energy, while click reaction between PMHS and V4 resulted in a strong glue of adjacent SNPs, endowing ORMOSIL hybrid coatings with good mechanical stability. Chemical-assembly engineering afforded ORMOSIL coatings superhydrophobicity, self-cleaning property, and good robustness, and the unique physical characteristic of ORMOSIL also gave superhydrophobic coatings excellent resistance to UV light, high and low temperature, and humid and salt mist environments. Finally, chemical-assembly engineering had been demonstrated to be applicable in fabrication of superhydrophobic coating on various substrates containing hydroxyl groups and various nanoparticles could be applied to replace SNPs.

Abstract ：
Rechargeable aqueous zinc-ion batteries (AZIBs) are promising candidates for stationary energy storage owing to their intrinsic safety, environmental sustainability, and cost-effectiveness. However, their cycling stability is hampered by uncontrollable dendrite formation and hydrogen evolution reactions (HERs) at the Zn anode. Herein, we propose a cost-effective commercial viscose fabric derived from profiled viscose rayons as a versatile separator for reconfiguring the interface dynamics of Zn deposition, enabled by the surface grooves with abundant carboxyl groups on the profiled viscose rayons. Results show that carboxyl groups facilitate the desolvation of hydrated Zn2+ to suppress HERs, while the surface grooves provide epitaxial Zn2+ pathways for rapid horizontal transport of Zn2+ on the surface of the Zn anode, which promotes the transition of the Zn deposition manner from 2D to 3D diffusion and regulates the growth direction of Zn crystals from (101) to (002) to form uniform and dense Zn deposition on the anode. Consequently, AZIBs implementing the viscose fabric separator exhibit high battery performance, including an improved cycle life of over 4600 h at 1 mA cm-2 and enhanced rate capability. This work highlights the significant potential of profiled viscose rayon in reconfiguring the interface dynamics of Zn deposition, providing guidance for the design of advanced separators in AZIBs.

Abstract ：
As a natural and sustainable high-strength material, bamboo has been widely used in modern architectural landscape and other aspects. Bamboo scrimber is a new engineered bamboo material obtained by a process of dissolving, dipping, and layer-by-layer hot pressing. It offers advantages of high strength, scalability, and versatility. However, bamboo is prone to mildew, which significantly limits the durability of engineered scrimber. In this study, bamboo fiber bundles were soaked in zinc acetate solution and then treated by atmospheric plasma. Zinc oxide nanoparticles were in-situ coated on the surface of bamboo through the high-energy reaction of atmospheric plasma, improving the mildew resistance of bamboo scrimber. Meanwhile, atmospheric plasma can effectively improve the wettability of the bamboo surface, allowing for the retention of the bamboo bark and bamboo inner skin those need to be removed in advance due to poor bonding performance in the preparation of bamboo scrimber. After atmospheric plasma treatment, the adhesive solution can better spread and penetrate the bamboo surface, forming a continuous and stable adhesive layer during the hot pressing process. The experimental results showed that bamboo scrimbers gained outstanding mildew resistance after atmospheric plasma treatment, along with a significant improvement in mechanical strength. This method is energy-saving and efficient, enabling pilot-scale and continuous production of bamboo scrimber, and holds great potential for widespread practical application. © 2025, The Authors.
