In this study, we produced microfibrillated lignocellulose (MFLC) from bleached chemithermomechanical aspen pulp using low-consistency refining (LCR) as a promising material for sustainable packaging. The MFLC was then converted into high-strength, water-resistant films with unique dual wettability—hydrophobic on one side and hydrophilic on the other—through casting, drying, and hot pressing. This opposing wettability naturally arises from the intrinsic hydrophobicity of lignin and its high interfacial energy with water, causing nano-lignin particles to accumulate at the film surface during formation. This feature provides promising potential for advanced packaging applications. Key packaging metrics—including mechanical strength, water vapor transmission rate, porosity, and thermal stability—were characterized. Increased thickness improved tensile strength and tear resistance, whereas hot pressing further improved tensile strength and thermal stability but reduced flexibility. These findings highlight MFLC produced though LCR as a promising precursor for bio-based packaging materials, particularly when high strength, thermal stability, and controlled surface hydrophilicity are required.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 11","pages":"6885 - 6907"},"PeriodicalIF":4.6,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07181-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional probe immobilization methods on cellulose are limited by uncontrolled orientation, instability, and poor reproducibility. To overcome these barriers, cellulose-binding modules (CBMs), non-catalytic domains of carbohydrate-active enzymes, have been engineered as versatile molecular anchors. Recent studies have demonstrated that CBM fusions with enzymes, antibodies, nanobodies, nucleic acids, and reporter proteins enable oriented, high-density, and stable immobilization on cellulose scaffolds, thereby transforming cellulose from a passive carrier into an active, programmable substrate. CBM-based biosensors have been successfully applied in colorimetric, fluorescent, electrochemical, and phage-assisted platforms, achieving detection ranges from femtomolar protein biomarkers to single-colony bacterial pathogens, as well as clinically relevant monitoring of metabolites such as glucose, uric acid, and lactate. These advances underscore the potential of CBM fusion technology to improve sensitivity, reproducibility, and robustness compared to conventional cellulose-based assays. Despite these promising developments, challenges remain in clinical validation, environmental stability, and integration into portable diagnostic devices. Addressing these issues through protein engineering, nanostructured cellulose materials, and device-level innovation is expected to accelerate the translation of CBM-enabled biosensors into practical applications for healthcare, environmental monitoring, and food safety.</p><h3>Graphical Abstract</h3><p>CBM-based functional materials for enhanced sensitivity, reproducibility, and robustness of biosensing applications</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 11","pages":"6437 - 6453"},"PeriodicalIF":4.6,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In pursuit of this goal, soybean hulls (SBH), an abundant agro-industrial byproduct, were valorized as renewable, per- and polyfluoroalkyl substances (PFAS) free biopolymer. A scalable acid-catalyzed thermochemical treatment yielded a water-soluble SBH powder, which was structurally and functionally characterized. The material exhibited zero volatile organic compound (VOC) emissions, high thermal stability up to 450 °C, and a glass transition temperature of 116 °C. FTIR confirmed polysaccharide- and lignin-derived functionalities that support hydrogen bonding, electrostatic interactions, and cohesive film formation. Rheological studies demonstrated shear-thinning behavior and viscosity of 240 cP at 25 °C. The 10 wt% solids content level for SBH was found to provide optimal balance between ease of processing, film strength, and barrier performance. When coated on recycled paper, and hardwood (HW) kraft pulp paper the oil and grease resistance fully improved from KIT #0 to #12. Water vapor transmission rate (WVTR) decreased by 9–15%, and tensile and burst index increased up to 40–50% compared to uncoated papers. In addition, the coated substrates exhibited favorable printability, characterized by uniform ink transfer, stable ink–substrate interaction, and consistent color reproduction, indicating compatibility with conventional printing processes such as flexography. The findings suggest that SBH could serve as a safe, non-toxic, versatile, and durable biopolymer for use in inks, coatings, paints and adhesives. Leveraging this low-value agricultural residue as a high-performance material may support circular economy strategies while helping reduce reliance on petroleum-based polymers.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 12","pages":"7275 - 7293"},"PeriodicalIF":4.6,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07194-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the optimized crystallinity achieved through crosslinking regulation, the cellulose membrane exhibits the best overall ion-management performance, delivering 3.69 W m⁻² in a 50-fold salinity gradient system, approximately 265% higher than that of the highly crystalline membrane. 13 series-connected single-membrane units provide stable outputs of 3.2 μA and 1.5 V for over 2500 s, supporting preliminary demonstrations of small-device operation and capacitor-assisted energy storage.

Specifically, carboxymethyl cellulose (CMC) serves as the matrix, which is combined with fines to reinforce the network structure. Fines are fragmented microscale pulp fractions separated from beaten bleached softwood pulp after screening with a 200-mesh sieve. And carbon black (CB) is introduced to enhance the conductivity, while Fe³⁺ is introduced for cross-linking to further strengthen the stability of materials, thus yielding the multifunctional CMC/fines/CB/Fe³⁺ composite foams.

Meanwhile, the foams also exhibit ultra-low density (0.0590 g/cm³), high porosity (90.3%) and low thermal conductivity (0.049 W/(m·K)). Crucially, the CMC/fines/CB/Fe³⁺ foams exhibit ultrahigh sensitivity (8.55 kPa⁻¹), which can work stably in both air and underwater environments, and maintain sensing stability after water immersion-drying cycles.
