Purpose : In this study, paying attention to the need for eyeglass frames with antibacterial function, silver nanoparticles were synthesized using polyvinylpyrrolidone (PVP), a polymer material, and coated on a metal eyeglass frame material substrates to evaluate antibacterial properties and coating properties.
Methods : Silver nanoparticles were synthesized by using PVP, a highly stable polymer material, as a reducing agent, dispersing agent, and stabilizer, and varying the synthesis temperature. The properties of the synthesized samples were analyzed using UV-visible spectrophotometer, SEM, EDS, and the antibacterial properties were evaluated by the paper disk diffusion method. The synthesized silver nanocolloids were coated on titanium and stainless steel substrates, which are metal eyeglass frame materials, and the properties and antibacterial properties of the coating film were measured.
Results : Silver (Ag) was detected in all samples synthesized using PVP, confirming the generation of silver nanoparticles. The size difference of silver nanoparticles according to the synthesis temperature was confirmed, and in the case of , , the silver nanocolloid synthesized at 45℃ showed the , and greatest antibacterial activity. After coating this on the metal eyeglass frame material substrates, the antibacterial properties were confirmed.
Conclusion : As a result of coating silver nanocolloids synthesized using PVP on a metal eyeglass frame material substrate, the antibacterial properties of the coating film were confirmed, suggesting that it could be used as an antibacterial material when manufacturing eyeglass frames with antibacterial function.
