Coating Thai Silk Fiber with CuO and CuO-Doped TiO2 Nanoparticles for Antimicrobial Properties
摘要
This study presents the synthesis and characterization of copper oxide (CuO) and copper oxide-doped titanium dioxide (CuO-doped TiO₂) nanoparticles applied to silk fabric to enhance its antimicrobial properties. The nanoparticles were synthesized using a hydrothermal reaction and applied to the silk fabric using dip-coating and impregnation techniques. The characterization was conducted through SEM, ATR-FTIR, and XRD to assess their distribution and binding. The antimicrobial activity was tested against Escherichia coli, Staphylococcus aureus, and Candida albicans using the agar diffusion method. The results of the research showed a significant inhibition zone of 16.66 mm for S. aureus and 20.44 mm for C. albicans with CuO-doped TiO2-coated silk, demonstrating superior antimicrobial efficiency compared to CuO alone. Durability tests revealed that silk coated with CuO-doped TiO2 retained 97.25% of its nanoparticle content after five washing cycles, outperforming CuO-coated silk. These results underscore the potential of CuO and CuO-doped TiO2 nanoparticles in developing durable antimicrobial textiles, contributing to advancements in biomedical and hygiene applications.
