Silver nanoparticles are in the spotlight in the field of high value-added new materials. Silver nanoparticles are widely used as antibacterial agents. Because they have an ability to penetrate bacterial cell walls, changing the structure of cell membranes and even resulting in cell death. In this study, the surface of PP fiber was coated with Ag nanoparticles by dip-coating in silver solution after plasma treatment. PP filter was treated via plasma instrument under various conditions, which best represents the hydrophilicity of the filter without damage. Ag solution was made with silver nitrate, citric acid, and sodium borohydride. Size of silver nanoparticle was controlled by various ratio of PVP as a stabilizer. Hydrophilicity of surface was confirmed with contact angel and particle size was confirmed by SEM. [본 결과물은 산업통상자원부와 한국산업기술진흥원의 "창의∙융합형 공학인재양성 지원사업"으로 수행한 결과물입니다.] |
