Amazonian palms, in particular, represent highly valuable but underestimated crops. Tensile tests are widely used to characterize the mechanical properties of biological materials, such as different plant organs. However, assessing their elastic properties from coupons requires accurate strain measurements, which remain challenging for such heterogeneous materials, thereby driving the development of advanced measurement techniques. This study focuses on the analysis of strain measurements using Digital Image Correlation (DIC), a non-contact optical technique that evaluates displacement fields from images captured during mechanical tests. Digital image correlation offers several advantages, including high spatial resolution, two-dimensional mapping of local strains, and non-intrusive measurement, while presenting challenges such as proper coupon positioning, image processing, accurate error quantification, and the assessment of experimental biases (e.g., offsets caused by edge curvature). This study evaluates the potential of DIC in assessing the tensile behaviour of leaflets of two Amazonian palm species (<em>Euterpe oleracea</em> and <em>Oenocarpus bataua)</em>, in comparison to laser extensometry. Repeated tensile tests allowed the estimation of the accuracy of DIC and its reliability for measuring strains, elastic moduli and Poisson’s ratios. The analysis revealed significant differences in elastic moduli and Poisson’s ratio between the two palm species, and spatial heterogeneity of full-field deformation within the leaflet coupons. Careful identification and exclusion of local artefacts were applied to obtain reliable measurements and ensure meaningful comparisons between the leaflets of the two studied species. Overall, these results confirm the potential of 2D-DIC for the mechanical analysis of plant materials, while also opening perspectives in understanding the relationships between anatomical structure of leaflets and their mechanical properties.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"245 ","pages":"Article 123248"},"PeriodicalIF":6.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147803610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignin, a naturally occurring biopolymer with low toxicity, offers considerable promise in this area; however, its practical use is limited by its inherently low antibacterial performance. In this study, kraft lignin (KL) was functionalized through free radical polymerization using three cationic monomers: [2-(methacryloyloxy)ethyl] trimethyl ammonium chloride (METAC), [2-(acryloyloxy)ethyl] trimethyl ammonium chloride (ATAC), and [3-(methacryloylamino)propyl] trimethyl ammonium chloride (MAPTAC). Among the resulting derivatives, KL-METAC demonstrated the highest charge density (3.76 mmol/g), along with superior solubility (96.4%), hydrophilicity, thermal stability, and UV-shielding capability. All cationic KL variants exhibited improved antibacterial performance against both Gram-positive and Gram-negative bacteria relative to unmodified KL, with KL-METAC and KL-MAPTAC showing the most pronounced activity, underscoring the influence of charge density on antibacterial efficacy. The potential applicability of KL-METAC—identified as the most promising derivative—was further validated through its incorporation into polyurethane (PU) films, which resulted in enhanced tensile strength (2.5–5.6 MPa), modulus (128–135%), water contact angle (52° to 62°), and UV resistance compared with pristine PU films. Remarkably, PU-KL-METAC films also exhibited elevated oxygen and water vapor permeability, indicating their suitability for breathable packaging applications, such as packaging for fresh produce. However, due to the presence of kraft lignin and its potential sulfur content, these materials are not intended for direct food contact. They are better suited for use in multilayer packaging systems, where a food-grade inner layer prevents direct contact. Further refinement of lignin derivatives is necessary to enable the development of lignin-based PU films for more demanding food packaging applications, such as dried products.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"19 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
