Composites containing 5–10 wt% RBLF were fabricated and their properties were compared with those of neat epoxy. The developed composites exhibited the following properties: tensile strengths ranging from 14.22 to 41.73 MPa, flexural strengths from 76.54 to 125.92 MPa, flexural moduli from 1.46 to 2.50 GPa, compressive strengths from 74.13 to 126.46 MPa, and compressive moduli from 2.67 to 4.03 GPa. These values compare favorably with those reported in the literature for conventional natural and synthetic fiber-reinforced composites, including jute/epoxy and flax/epoxy systems, which were tested under similar conditions. Water absorption increased from 0.85–1.34% after 24 hours to 1.18–4.33% after 384 hours, reaching an almost constant value after 96 hours. The composites were further characterized using several methods: Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and three-dimensional surface topography analysis. The FTIR spectra confirmed effective cross-linking within the leather fiber/epoxy composites, as evidenced by the characteristic absorption bands at 2923–2924, 2852–2854, and 1455–1460 cm^{− 1}, corresponding to CH/CH₂ stretching vibrations. In addition, EDX analysis revealed that chromium, nitrogen, sodium, phosphorus, aluminum, and silicon, which were detected in the raw leather, were no longer observed in the composites, indicating that the leather fibers were effectively encapsulated by the epoxy matrix. Overall, these results demonstrate that recycled bovine leather fiber/epoxy composites represent a promising lightweight material for weight-sensitive applications.</p></div>","PeriodicalId":576,"journal":{"name":"Functional Composite Materials","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s42252-026-00102-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When combined with atomic force microscopy (AFM), it is useful strategy to analyze morphology. Optimisation of the LbL technique is bottlenecked by manual sample preparation, and there is also a lack of standardised analytical pipelines to convert characterisation data into machine-readable descriptors. We address both bottlenecks by combining a collaborative robotic dip-coating platform with an automated feature-extraction backend for AFM topography. The robotic arm handles the substrate (Si wafer), immerses it in polyelectrolyte solution, and prepares samples for AFM study without operator intervention. Resulting AFM scans are transferred into a reproducible pipeline that applies a logged preprocessing chain and computes twelve groups of physically interpretable descriptors per sample: ISO 25,178 areal roughness, height-distribution statistics, radial power spectrum with Hurst and fractal exponents, two-dimensional autocorrelation, local-patch minima/maxima distributions, persistent homology of patch point clouds, gliding-box lacunarity, and a recipe-derived block of layer composition, sequence k-grams and RDKit monomer descriptors. Every descriptor is stored with the originating method version and parameters, supporting idempotent recomputation and side-by-side methodological evolution. The pipeline was applied to polyethyleneimine (PEI)/polystyrene sulfonate (PSS) assemblies on Si substrates, and an unsupervised principal component projection of the scalar descriptors already separates samples by the number of deposited layers, demonstrating that the resulting feature vectors carry coating-state information at a level useful for downstream machine learning. This work establishes a traceable, data‑driven bridge from synthesis instructions to high‑dimensional surface descriptors, demonstrating for the first time an end‑to‑end pipeline where robotic LbL assembly, versioned AFM processing, and hybrid topological‑chemical feature extraction converge into a single machine‑learning‑ready dataset.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":576,"journal":{"name":"Functional Composite Materials","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s42252-026-00103-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TPUs have a unique segmented structure featuring soft and hard segment alternation, which contributes to their inherent tailor-made flexibility and strength. Incorporation of the graphene fillers enhanced the thermal stability, mechanical performance, and electrical conductivity by virtue of their large surface area.

GO and RGO decreased oxygen permeability by approximately 70% and 46%, respectively. RGO exhibited enhanced mechanical and electrical properties attributed to reduced oxygen content and increased π–π interactions. At 1.0 wt%, GNP established a percolated conductive network exhibiting an electrical conductivity of approximately 9.0 × 10^− 5 S/m, which is 66% greater than that of RGO filled composites.

In this study, graphene nanoplatelets were incorporated at low loadings (0.1, 0.3, and 0.5 phr) into SBR to evaluate their effect on vulcanization behavior, thermal stability, hardness, and wear resistance. Graphene incorporation increased the crosslink density of SBR by up to 17% but did not significantly affect curing kinetics, with all formulations showing an optimum cure time of approximately 18 min. Thermal analysis revealed no significant changes in the main degradation pathways of SBR, although the increase in glass transition temperature suggests restricted chain mobility. Shore D hardness increased with increasing graphene content, rising from 31 at 0 phr to 33.4 at 0.5 phr, confirming the reinforcing effect of graphene nanoplatelets at low concentrations. Wear performance, evaluated by both mass-loss and volume-loss abrasion tests, demonstrated a clear reduction in wear with increasing graphene content. The best performance was observed for 0.5 phr graphene, where mass loss decreased up to 26% compared to neat SBR. These results contrast with previous studies that reported deterioration in abrasion resistance at higher graphene loadings, supporting the hypothesis that graphene acts as a reinforcing filler only at low concentrations.

The primary objective was to determine the optimal annealing temperature that enables the full development of the composite’s structural and textural properties while preserving the metal iodide crystals. The physicochemical characteristics of the HPs were evaluated using various analytical methods, with the retention of AgI and ZnI₂ phases, specific surface area, and pore parameters serving as key control indicators.The results confirm that the morphology of the AgI-MCM48-ZnI₂ HPs is governed by the structural features of the unmodified MCM-48 matrix. It was demonstrated that reducing the annealing temperature to 550 °C allows for a 25 wt% increase in the zinc iodide content within the HPs while effectively preventing the formation of undesired zinc oxide. Furthermore, this optimized temperature regime contributed to a 1.5–2.0-fold increase in both specific surface area and pore diameter. The incorporation of zinc iodide was shown to significantly enhance the thermal stability of silver iodide.

However, in the era of sustainability, extensive application of thermoset-based FRP composites is limited due to their poor recyclability, which poses an environmental threat.
