Abstract
En 中文
Cotton textiles (CTs) are in high demand for antimicrobial applications. Traditional approaches often struggle to achieve antibacterial and antifungal efficacy simultaneously. Herein, organosilicon quaternary ammonium salt (QAS/AEM-5700, a contact bactericidal agent) and organosilicon borneol ester (SBA, a stereochemical anti-adhesive agent) are covalently co-grafted onto CT surfaces via siloxane hydrolytic condensation, generating a synergistic antimicrobial coating (CT-A/S) that integrates both offensive and defensive functionalities. The as-prepared CT-A/S exhibits excellent antimicrobial activity against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and Aspergillus niger (A. niger), with antimicrobial rates approaching 100%. Owing to the covalent immobilization, the CT-A/S demonstrates outstanding laundering durability. This strategy not only overcomes the deficiency of QAS-modified CT in mold resistance, but also addresses the limitation of borneol ester in contact-based bacterial killing. Furthermore, an in vivo mice infection model validates the antibacterial and anti-infective efficacy of the coating, offering a promising approach for the long-term antimicrobial protection of healthcare textiles.
