It was then added to a cellulose/ 1-Allyl-3-methylimidazole chloride (AMIMCl) solution to form a liquid crystal system to reduce viscosity. The liquid crystal properties of the cellulose/CaB/AMIMCl solutions were characterized using a polarizing microscope, torque rheometer and fourier transform infrared spectroscopy. The results showed that the liquid crystal phase appeared in a solution consisting of 3wt% CaB and 6wt% cellulose at temperature from 30 to 60 °C. The liquid crystal dopes were then spun into cellulose/CaB blended fibers by dry-jet wet spinning method. The structure and properties of the fibers were characterized through scanning electron microscopy, x-ray diffractometer, single-fiber strength tester and UV testing. Compared to pure cellulose fiber, the blended fiber exhibited an increase in crystallinity, a 57.2% improvement in breaking strength, and an 80.8% reduction in UV transmittance.

However, chitin nanowhiskers (ChNWs) exhibit inferior reinforcing ability because of their mediocre modulus values, necessitating focus on other features to boost applicability. In this study, salicylic acid (SA) was grafted onto the surface amino groups (SAGs) of ChNWs and deacetylated ChNWs (DaChNWs) to obtain SA-grafted NWs via condensation amidation. The reaction time and SA/SAG stoichiometric ratio were varied to control the amount of grafted SA, which was quantified by titration of residual SAGs and ultraviolet (UV) absorption measurements of the grafted NWs after dissolution. Under similar conditions, the magnitude of SA grafting (20–167 mmol/g<sub>NWs</sub>) was greater than that of propionic acid (PA). The ChNWs, DaChNWs, and their SA-grafted counterparts were incorporated into poly(vinyl alcohol) films, realizing nanocomposite films with improved modulus, strength, and UV-shielding performance, enabled by both SA grafting and inherent scattering by the NWs. Soaking cotton fabrics in aqueous SA-grafted-NW suspensions and subsequent drying readily yielded NW-coated fabrics, which exhibited outstanding UV-shielding performance owing to SA grafting, and enabled deodorization of gaseous acetic acid via ionic interaction with residual SAGs. Our findings underscore the utility of SA-grafted (Da) ChNWs as nanofillers/finishes with multiple functionalities (reinforcement, UV shielding, and deodorization).</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":"32 6","pages":"4057 - 4075"},"PeriodicalIF":4.9,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908828","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}

The research’s primary focus was the conversion of carboxymethyl cellulose (CMC) derived from agricultural waste into a bioplastic film that is satisfactory for use in packaging. The weak mechanical stability and excessive water sensitivity of CMC films limit their widespread use. To overcome these limitations, therefore, CMC films were reinforced with varying concentrations (0, 5, 10, 15, 20, and 25%) of zinc oxide nanoparticles (ZnO NPs), using a solution casting method. The films were also surface-modified by spray coating with a 1:1 composite mixture of poly(dimethylsiloxane) (PDMS) and starch. An array of analyses were used to investigate the films’ properties. Structural characterization employing Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) confirmed the successful incorporation of ZnO and uniformity of PDMS/starch coating on the films. Thermogravimetric analysis (TGA) and mechanical testing revealed that the films’ thermal and mechanical properties were improved by the incorporation of ZnO, with the film CZ<sub>20</sub>-C exhibiting the highest value of tensile strength––14.029 MPa––and 27.59% elongation at break. The films exhibited excellent water resistance, as evidenced by a remarkable increase in their water contact angle to 152.04°. Furthermore, biodegradability studies demonstrated that the films degraded by 84.78% in soil within 20 days, under ambient conditions. Films with these desirable characteristics are therefore producible through the study’s facile strategy for preparing CMC-based eco-friendly composite films that have excellent potential to replace conventional plastic in the packaging industry.</p><h3>Graphic abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 6","pages":"3833 - 3853"},"PeriodicalIF":4.9,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908726","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}

This study demonstrated that, following pectin depolymerization, partial xylan and mannan in the middle lamella and phloem parenchyma could be removed in their non-depolymerized forms. Thus, the bio-degumming process followed by mechanical beating was improved by an alternating approach. Ramie bast was first beaten to loosen the middle lamella and phloem parenchyma, aiding pectinase, xylanase, and mannanase binding to internal gums. These enzymes then partially degraded the gum, weakening gum-fiber connections. Additional beating removed these loosened tissues, accelerating primary wall exposure. This approach reduced the blocking effect of gum laminated junctions, shortening degumming time. Afterward, carbohydrate binding domains further weakened the hindering effect of side chains and enhanced endoxylanase and endomannanase to remove residual hemicellulose on the primary wall. Furthermore, the engineered <i>Pectobacterium carotovorum</i> HG-49 capable of constitutively expressing and secreting the fusion proteins of endoxylanase, endomannanase, and carbohydrate binding domains was built. The alternating treatment with the engineered HG-49 and mechanical beating reduced degumming time from 16 to 12 h, decreased residual gum content from 6.34 to 4.48%, and cut alkali use by 83%. The breaking strength of fiber bundles increased from 4.05 to 5.01 cN/dtex, and the wastewater was suitable for reuse in cultivating <i>Mortierella alpina</i> synthesizing arachidonic acid for feed.
