The combination of sequence of chemical and enzymatic pretreatment for CNF production had been poorly investigated, especially complementing them with cellulose functionalisation, such as phosphorylation. In this study CNF were obtained by a three-stage pre-treatment carried out on bleached eucalyptus kraft pulp (BEKP) as follows: a) cold caustic extraction with 15% NaOH (CCE15), b) enzymatic treatment with 50 U <i>Trichoderma reesei</i> endoglucanase (EG) and c) functionalisation by chemical phosphorylation (P) with urea and di-ammonium hydrogen phosphate. Pulps obtained from the different combinations were characterised for properties such as crystallinity, viscosity, S18 solubility, fibre morphology, FTIR, SEM and SEM–EDX to determine differences between samples and treatments. CNF of selected samples were prepared by homogenisation and characterisations were performed on drop cast films prepared from them. The main results showed that the opacity of the films varied between 14%–67%, the water vapour permeability varied between 163–322 g/m<sup>2</sup>.day, the burst index was in the range of 2.0–3.3 kPa.m<sup>2</sup>/g, the tensile strength was between 6–120 MPa and the films made from phosphorylated CNF were air-impermeable. In conclusion, the combination of chemical-enzymatic pretreatments did not lead to a facilitation in CNF production compared to just performing phosphorylation or enzymatic treatment. Though, different CNF material properties can be obtained varying the pretreatments combination stages, which can be beneficial to implement if the goal is to produce CNF materials with special properties depending on the purpose.</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 18","pages":"10931 - 10949"},"PeriodicalIF":4.9,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753904","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 benzoxazine monomers were synthesized using eugenol, furfuryl amine or stearyl amine, and paraformaldehyde (E-fa and E-sa) by a solvent-less, green synthetic approach. The synthesized benzoxazine monomers were characterized by FTIR and <sup>1</sup>H NMR. Trifunctional benzoxazine monomers were synthesized by a simple thiol-ene click reaction using E-fa, E-sa, and trithiocyanuric acid. Later, the hydrophobic cotton fabric or filter paper was prepared by a simple dip coating method using E-fa, E-sa, E-fa/TCA, and E-sa/TCA separately, followed by thermal curing. The hydrophobic PBZ coated on the fabric/filter paper materials revealed better separation of emulsified oil–water mixtures with a separation efficacy of > 98% even after 15 repeated cycles. The thermal behavior of developed PBZ showed better thermal stability (thermal degradation and higher char yield) than conventional bisphenol A and F based PBZs. The hydrophobic/oleophilic surface on the cotton fabrics/filter paper, altered with the sustainable bio-based eugenol-based benzoxazines, is eco-friendly and easy to scale up, revealing prodigious capacities in several practical applications including oil–water separation and self-cleaning.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 18","pages":"11169 - 11184"},"PeriodicalIF":4.9,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753929","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}

However, modern pesticide applications contaminate air, water, soil, and unintentional target species. It is necessary to develop effective and sustainable methods to detect different pesticides within our environment. Surface-enhanced Raman spectroscopy (SERS) has garnered significant attention for its ability to detect and quantify environmental contaminants, as it is a rapid and sensitive technique that requires minimal sample preparation. The present study demonstrates the development of a biowaste-derived nanocellulose-based thin-film that, when integrated with gold nanoparticles, produces a sustainable and reproducible SERS nanosubstrate. In this study, three pesticides (carbaryl, ferbam, and thiabendazole) were sensitively and selectively detected by the combined use of this novel nanocellulose-based SERS nanosubstrate and a portable Raman instrument. The limits of detection were determined to be 1.34, 1.01, and 1.41 mg/L for carbaryl, ferbam, and thiabendazole, respectively, all of which are well below the agricultural application concentrations recommended. SERS signals were collected for both prepared ferbam spray solution and collected sprayed droplets, and it was found that there is no major difference in the signals, indicating that this detection method is reliable to detect pesticide droplets. A commercial pesticide was detectable by the biowaste-derived SERS nanosubstrate. This study is among the first to utilize biowaste-derived nanocellulose to create SERS nanosubstrate for pesticide detection in spray droplets. We demonstrate the high potential of biowaste-derived nanocellulose in combination with the portable Raman technique for agricultural pesticide spray detection.</p><h3>Graphical abstract</h3><p>\u0000(Image was created with BioRender.com.)</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 18","pages":"10915 - 10929"},"PeriodicalIF":4.9,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753902","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}
