“…Paper- and cotton-based materials are gaining growing interest in a wide range of applications owing to their inherent advantages such as widespread availability, affordability and eco-friendliness [ 52 ]. The CDs were attached to cellulose fibres (cotton or paper) by direct incubation of the fibres with the CD solution at neutral pH, as detailed in §2.3.…”

This study focuses on the development of antimicrobial fibres for use in medical and healthcare textile industries. Carbon dots (CDs) were designed with boronic acid groups for the attachment to cellulose fibres found in cotton textiles and to enhance their attachment to glycogens on bacterial surfaces. Boronic acid-based and curcumin-based CDs were prepared and characterized using various techniques, showing a nanoscale size and zeta potential values. The CDs inhibited the growth of both Staphylococcus epidermidis and Escherichia coli bacteria, with UV-activated CDs demonstrating improved antibacterial activity. The antimicrobial activity of the CDs was then tested, revealing strong adherence to cellulose paper fibres with no CD diffusion and potent inhibition of bacterial growth. Cytotoxicity assays on human cell lines showed no toxicity towards cells at concentrations of up to 100 µg ml −1 but exhibited increased toxicity at concentrations exceeding 1000 µg ml −1 . However, CD-modified cellulose paper fibres showed no toxicity against human cell lines, highlighting the antimicrobial properties of the CD-modified cellulose fibres are safe for human use. These findings show promising potential for applications in both industrial and clinical settings.

“…Paper, composed of cellulose, is a substantial and environmentally friendly material known for its plasticity, degradability, and recyclability. Its versatility nds applications in packaging, furniture, and other elds (Wen and Guo 2020; Zhang et al 2023). However, the inherent hydrophilicity and ammability stemming from natural cellulose bers limit its service life and potential applications (Li et al 2022).…”

The water absorption and flammability of paper pose significant challenges for its long-term effectiveness. In addressing these concerns, a paper modification strategy was proposed that synergistically incorporated superhydrophobicity and flame retardancy. This approach involved the formation of a micro or nano-level rough structure on the paper surface through sodium silicate modification. Subsequent modification with polydimethylsiloxane (PDMS) resulted in a functional paper, exhibiting excellent superhydrophobic properties. The water contact angle (WCA) and sliding angle (SA) of the modified paper reached 153.5° and 9°, respectively, exhibiting excellent self-cleaning ability and wear resistance. The results from TG–DTG analysis and cone calorimeter tests indicated that the superhydrophobic paper exhibited remarkable thermal stability and flame-retardant properties. These properties contributed to enhancing the safety of products during application. The comprehensive improvement in paper properties, including its superhydrophobicity, flame retardancy, and thermal stability, holds significant implications for expanding its application range and enhancing its overall utility.

Petroleum‐based compounds are widely used to enhance the hydrophobicity of paper but compromise its biodegradability. The development of biocompatible natural materials for the hydrophobic treatment of paper is of great significance. This study used corn starch (St) as raw material and prepared double‐modified starch (PT‐St) through dual modification of polyethyleneimine (PEI) and tetradecyl succinic anhydride (TDSA). The conditions for double modification starch were optimized through single‐factor and orthogonal experiments. The effects of PT‐St modified starch on the mechanical properties, hydrophobicity, and barrier properties of different paper types were studied. The results showed that the tensile index of 100% waste pulp (WEP), wood pulp (hardwood pulp: softwood pulp = 7:3) (WDP), and 100% bamboo pulp (BOP) coated with PT‐St increased by 44.11%, 37.41%, and 20.39%, respectively, and the contact angle was 118.42°, 120.17° and 122.37°, respectively. The water vapor transmission rate decreased by 35.03%, 20.32% and 21.83%, respectively. This new hydrophobic‐enhanced modified starch has considerable potential application potential in food packaging paper.
