Inspired by the charge-secreting layer of <i>Sandcastle worm</i> and the asymmetric wettability of lotus leaf, we successfully developed a dual biomimetic cellulose-based packaging material (CW@(CT)₁₀). This material was achieved through an electrically charge-controlled layer-by-layer self-assembly of chitosan and titanium dioxide nanoparticles (TiO₂ NPs), followed by functionalization with carnauba wax (CW). The material achieved commendable mechanical properties and abrasion resistance, rendering it highly stable and durable. Benefitting from the rough surface with nanostructures and low surface energy, the CW@(CT)₁₀ showed a high water contact angle of 152.14°. The superhydrophobic surface reduced the bacterial adhesion, which integrated with the electropositivity of chitosan, endowing the materials with a 100% antibacterial ability to <i>Staphylococcus aureus</i> and <i>Escherichia coli</i>. Fruit antimicrobial tests and degradation studies in the natural environment demonstrated that CW@(CT)₁₀ kept fruit bacteria-free for 5 days and were completely biodegraded within 100 days. Notably, this work introduced a facile strategy for scalable production of a sustainable, inexpensive, durable, and environmentally friendly material, showcasing immense potential applications in food packaging.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 17","pages":"10445 - 10462"},"PeriodicalIF":4.9,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672412","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}

Society has become aware of the need to replace or substitute environmentally persistent synthetic polymers, and cellulose has received a large amount of attention in this respect. The mechanical properties of cellulose, its renewable nature and biodegradability are advantageous properties. Drawbacks exist for the use of plant cellulose (PC), including the water footprint of cotton, deforestation associated with wood/dissolving pulp, and the extensive processing required to refine plants and wood into pure cellulose. Bacterial cellulose (BC), also known as microbial cellulose, is gaining momentum in both academic and industry settings as a potential solution to the many drawbacks of plant-based cellulose. Compared to PC, BC has high purity, crystallinity and degree of polymerisation, and can be manufactured from waste in a way that yields more cellulose per hectare, per annum, and requires less intense chemical processing. Native bacterial cellulose can be formed and shaped to an extent and is found in a variety of commercial products. However, dissolving and regenerating bacterial cellulose is a potential avenue to broaden the applications available to this material. The aim of this study is to review the applications which utilize regenerated bacterial cellulose, with a focus on the dissolution/regeneration methods used and discussing the associated limitations and future outlook.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 17","pages":"10165 - 10190"},"PeriodicalIF":4.9,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-024-06220-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672411","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}

Film alignment was qualitatively assessed using cross-polarized optical microscopy and quantified by order parameters computed by UV–Vis transmission spectroscopy. Electrolyte addition resulted in an increased alignment in dried CNC films. For pure CNCs, the film order parameters remained constant at approximately 0.3 for shear rates from 20 s⁻¹ to 100 s⁻¹. However, higher order parameters were achieved in the presence of electrolytes. Notably, an order parameter of 0.88 was achieved at a shear rate of only 20 s⁻¹.

The results of this work highlight that electrolyte addition can enable higher order parameters at lower shear rates and facilitate the development of aligned CNC films for applications such as polarizers, clear coatings, and piezoelectric materials.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 17","pages":"10271 - 10284"},"PeriodicalIF":4.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-024-06204-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672618","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}

The unclear reaction behavior of solid acid catalytic cellulose acetylation results in limited success of previous efforts and measures. In the present work, SO₄²⁻/TiO₂ solid acid was used as the research object in comparison with H₂SO₄. Various characterization results demonstrate that the reaction behavior of cellulose acetylation catalyzed by SO₄²⁻/TiO₂ is completely different from that by H₂SO₄. SO₄²⁻/TiO₂ is limited to the outer surface of cellulose for catalytic acetylation through solid-to-solid contact, while H₂SO₄ can penetrate into the cellulose interior for internal and external simultaneous acetylation. The superficial cellulose molecular chains undergo partial acetylation by SO₄²⁻/TiO₂ catalysis and subsequently dissolve in acetate acid, followed by being further catalytic acetylated. The subsurface cellulose molecular chains are exposed to interact with SO₄²⁻/TiO₂ for subsequent round of acetylation till the depletion of the celluloses. Based on the present research result of reaction behavior, it is clarified that the efficiency of solid acid catalytic cellulose acetylation is mainly determined by the micron-scale morphological limitation between solid acid and cellulose rather than the intrinsic catalytic activity of solid acid.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 17","pages":"10285 - 10302"},"PeriodicalIF":4.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672607","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}

For such purpose, four hardwoods (Beech, European Hop Hornbeam, Turkey Oak and Paulownia) and one softwood (Corsican Pine) have been selected on the basis of their anatomical features, density, and potential exploitation of natural resources. The goal is to evaluate and compare the properties of delignified woods derived from the selected species for the fabrication of wood-polymer hybrids, including transparent wood products. Wood samples of different cut (longitudinal or transversal) and thickness (1 mm or 3 mm) were soaked in an alkaline sulfite solution and mildly bleached in hydrogen peroxide. Dry mass loss was determined in different experimental conditions. Macro- and microstructure of delignified woods have been investigated by optical microscopy, scanning electron microscopy, infrared spectroscopy and X-ray diffraction analysis. Thermal degradation profiles were acquired by thermogravimetry, the total transmittance measured in the UV–Vis range and mechanical properties evaluated by tensile tests. The dry mass loss ranged within 26–52%. Delignified hardwoods showed enhanced optical transmittance especially Paulownia (+ 80%) and Turkey Oak (+ 140%), characterized by large vessels and thin cell walls, while the macro- and mesostructure along with tensile properties were preserved.
