Purpose: In this study, after synthesizing silver nanoparticles, they were coated on Ultem (polyetherimide: PEI), a material for eyeglass frame, to evaluate antibacterial properties and coating properties.
Methods: After synthesizing silver nanoparticles using AgNO3 (silver nitrate) and PVP (polyvinylpyrrolidone), a characteristic surface plasmon resonance absorption band was confirmed using a UV-visible spectrophotometer. In addition, the size, shape, and composition of the synthesized samples were analyzed using SEM and EDS. The synthesized silver nanoparticles were stirred with an acrylate-based coating binder, then coated on an Ultem substrate, a material for eyeglass frame, and the properties and antibacterial properties of the coating film were measured.
Results: As a result of measuring the absorbance to confirm the synthesis of silver nanoparticles, a maximum absorption peak was observed around 400 nm. In addition, it was confirmed that the peak increased as the synthesis time increased. The silver nanoparticles confirmed through SEM were formed in triangular and hexagonal crystals of about 20 to 80 nm, and as a result of EDS analysis, 75.89% of silver and 24.11% of carbon were found in the sample, confirming the formation of silver nanoparticles. In addition,the adhesion and antibacterial properties of the coating film were excellent
Conclusions: The coating film coated on Ultem, a material for eyeglass frame using synthesized silver nanoparticles, showed excellent antibacterial properties against Escherichia coli, confirming the possibility of manufacturing eyeglass frame with antibacterial function.
