Here, we present an asymmetrically designed, cellulose-based bilayer film that satisfies all those requirements and can be produced in a simple and environmentally friendly manner. The wound-facing side of this film features excellent adhesive properties brought about by a biocompatible catechol functionalization of carboxymethyl cellulose and promotes blood coagulation while avoiding hemolysis. In contrast, the outer side of the film has bacteria-repellent properties, which are established by the anti-bacterial glycoprotein mucin, integrated into a fibrous cellulose matrix, that can be covalently crosslinked. In addition, the construct can act as a drug reservoir and decomposes in a wet environment. These properties render the bilayer film a promising candidate for applications in wound closure, particularly for lesions encountered in intestinal or ocular tissues.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 6","pages":"3899 - 3917"},"PeriodicalIF":4.9,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06486-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908714","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}

In this study, the preservation mechanism of jute fibers derived cellulose nanofibril (CNF) coatings for banana storage was explored in terms of both chemical composition and particle size. In terms of chemical composition, the CNF coating prepared from raw jute fibers was most suited for use in banana storage, mainly due to its higher antioxidant and UV protection properties. In terms of particle size, the CNF coating homogenized for 5 passes achieved the best performance in preserving the freshness of bananas, mainly owing to its better oxygen barrier properties. The possible preservation mechanism of jute fibers derived CNF composite films for banana storage is related to the formation of a highly dense structure attributed to the strong hydrogen bonding between cellulose molecules and the plugging effect of noncellulosic components, offering excellent antioxidant, UV resistance, and oxygen barrier properties.

Mechanical testing revealed that composites with recycled cellulose fibers outperformed those with cellulose acetate, exhibiting a flexural modulus of 3527.7 MPa and a flexural strength of 24.2 MPa, compared to a flexural modulus of 1411 MPa and a flexural strength of 13.4 MPa for cellulose acetate. Shear strength tests also showed superior results for recycled cellulose (5.7 MPa) compared to cellulose acetate (3.3 MPa). Charpy impact tests further confirmed this trend, with impact strengths of 8.1 kJ/m<sup>2</sup> for cellulose and 6.7 kJ/m<sup>2</sup> for cellulose acetate. These findings highlight the potential of cellulose-reinforced casein composites as eco-friendly alternatives to synthetic materials, addressing both milk waste and cigarette pollution.

Among different types of natural polymers, xylan has advantages of abundance, easy separation, good water solubility/dispersibility, high affinity to paper fibers, good reactivity and unique rheological properties, making it a significant candidate. However, how to effectively assemble the water dispersible xylans and the water indispersible hydrophobic nano-particles onto hydrophilic paper surface has become a problem in super-hydrophobic surface construction. In this study, xylans were modified with dodecene succinic anhydride (DDSA) and hexadecene succinic anhydride to improve their hydrophobicity, which were then coated onto paper surface and used to adsorb silica nanoparticles in ethanol. A rough micro-nano structure was successfully fabricated on paper surface and a super-hydrophobic paper surface with water contact angle up to 157° was successfully obtained. The degree of substitution of the modified xylans has great influence on the super-hydrophobic surface construction. DDSA modified xylan with DS of ~ 0.2 has the highest affinity to silica nanoparticles and is able to construct super-hydrophobic paper surface after adsorbing silica nanoparticles. The super-hydrophobic paper surfaces have strong durability and maintain super-hydrophobicity after storing under room environment for 66 days or 100 times of surface friction. The superhydrophobic paper surfaces have good acidic stability but poor alkaline stability.
