Abstract Aerogels, renowned as ultra-lightweight solids with exceptional porosity and specific surface area, have emerged as pivotal materials for thermal insulation, catalysis, energy storage, and biomedicine. This review comprehensively evaluates the recent strides in sustainable, high-performance cellulose-based aerogels, emphasizing their fabrication, functionalization, and application prospects. It details the extraction of cellulose from diverse sources and its subsequent processing into nanocellulose (e.g., cellulose nanofibrils and nanocrystals), which serves as the fundamental building block for aerogel synthesis. The critical sol-gel transition, solvent selection, and the pivotal role of drying techniques—freeze-drying, supercritical drying, and ambient pressure drying—in determining final… More >

Abstract Formulating oil-based drilling fluids (OBDFs) with an ultra-low oil-to-water ratio (OWR ≤ 60:40) presents a formidable stability challenge due to the maximized interfacial area and intensified stress on the interfacial film under high-temperature, high-density conditions. To address this, we engineered a synergistic stabilization system through molecular and colloidal design. A novel hyperbranched polyamide emulsifier (epoxidized soybean oil polyamide) (ESOP), synthesized from epoxidized soybean oil, exhibits superior thermal stability and interfacial activity due to its hyperbranched architecture. Combined with calcium petroleum sulfonate (CPS) and hydrophobic nanosilica (HNs), it enables a high-performance OBDF with an ultra-low OWR… More >

Abstract The demand for extended electric vehicle (EV) range necessitates advanced lightweighting strategies. This study introduces a materials genome approach, augmented by machine learning (ML), for optimizing lightweight composite designs for EVs. A comprehensive materials genome database was developed, encompassing composites based on carbon, glass, and natural fibers. This database systematically records critical parameters such as mechanical properties, density, cost, and environmental impact. Machine learning models, including Random Forest, Support Vector Machines, and Artificial Neural Networks, were employed to construct a predictive system for material performance. Subsequent material composition optimization was performed using a multi-objective genetic More >

Abstract This study presents a sustainable approach for the valorization of spent coffee grounds (CG) by converting them into carboxylated cellulose nanofibrils (CG-TCNF) via formic acid/hydrogen peroxide pretreatment followed by TEMPO/NaClO/NaClO₂-mediated oxidation. The pretreatment efficiently removed lignin, hemicellulose, and other non-cellulosic components, yielding purified cellulose (CG-C) with high crystallinity (CrI = 84%). Subsequent regioselective oxidation introduced carboxyl groups at the C6 position of cellulose chains, achieving a high carboxylate content of 1.4 mmol/g. The resulting CG-TCNF exhibited a well-dispersed nanofibrillar morphology with an average width of 3.57 nm and a high specific surface area of 265 m²/g. More >

Abstract Polyurea (PUA) is widely valued in protective coatings and structural reinforcement because of its impressive mechanical strength and resistance to corrosion. Its high flammability, together with the poor dispersion that often comes with simply blending in flame retardants, continues to limit its use in demanding environments. To overcome these issues, this study introduces a different approach. We grafted 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) onto the surface of a metal–organic framework (MOF) and then partially amino-functionalized the DOPO layer, ultimately creating an amino-modified DOPO–MOF hybrid. The introduced amino groups can directly react with the isocyanate (–NCO) groups in the… More >

Abstract A comparative analysis was performed on poly(lactic acid) (PLA), poly(caprolactone) (PCL), basalt fiber (BF) composites produced using two distinct approaches: direct blending and masterbatching. The limitations of PLA-BF composites with regard to distribution and adhesion are well-documented, as are chemical treatment methods (addition of compatibilisers, surface treatments, silanization). This work aimed to study an industrially relevant potential solution of utilising a PCL-BF masterbatch, prepared as a 50/50 wt.% blend using planetary roller extrusion (PEX) to both improve the distribution and homogeneity of the fibers as well as provide a secondary adhesion site to facilitate improved… More >

Abstract Epoxy resins are extensively employed in the construction, electronics, automotive, and aerospace industries owing to their outstanding mechanical strength, chemical resistance, and electrical insulation. However, their intrinsic flammability, poor wear resistance, and hydrophilicity significantly restrict broader applications. To address these challenges, a novel multifunctional coating (CEOS-DOPO-PDMS) has been designed and fabricated via an NP-GLIDE approach. The system integrates 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) as a reactive phosphorus-based flame retardant, epoxy-terminated polydimethylsiloxane (EP-PDMS) as a hydrophobic segment, and cycloaliphatic epoxy-functionalized oligosiloxanes (CEOS) as a cross-linking co-reactant. The resulting CEOS-DOPO-PDMS hybrid precursor was blended with bisphenol A diglycidyl ether (DGEBA)… More > Graphic Abstract

Abstract Phenolic resins are widely used in thermal protection, yet achieving simultaneous improvement in thermal stability and mechanical strength remains challenging. In this work, a vinyl-modified silicone resin (VMTQ) was synthesized and incorporated into a boron phenolic resin (BPF) matrix. Three composite ceramic fillers, Al₂O₃–SiO₂–ZrO₂ (ASZ), Al₂O₃–SiO₂–TiO₂ (AST), and Al₂O₃–SiO₂–MgO (ASM), were further introduced to construct a multi-oxide synergistic reinforcement system. Thermogravimetric analysis shows that the maximum decomposition rate decreases by 0.2–0.3%·min⁻¹, while the ASM/V3/BPF-3 composite exhibits a 74.53% increase in char yield at 800°C and a 163.3°C increase in initial decomposition temperature, confirming its significantly enhanced thermal More >

Abstract To meet the needs of the treatment of Cu²⁺ pollution in aqueous solution, the sodium alginate-modified polyacrylic acid (PAA/SA) composite hydrogel was prepared by solution polymerization with acrylic acid (AA) as monomer, sodium alginate (SA) as filler, N, N’-methylenebisacrylamide (MBA) as crosslinking agent, and potassium persulfate (K₂S₂O₈) as initiator. The characterization results showed that the introduction of SA significantly improved the physical and chemical properties of PAA hydrogel materials. Scanning electron microscopy (SEM) showed that as the SA content increased, the materials gradually evolved from a dense blocky structure to a porous network. When the SA… More >
