Application of Terminalia catappa in Preparation of Silver Nanoparticles to Develop Antibacterial Nylon

Preparation of silver nanoparticle by using leaf extracts of Terminalia catappa, its deposition on Nylon fabrics, and the modification with an addition of HDTMS have been conducted in this research. The samples prepared in this study were nylon cloth (N0), nylon cloth silver nanoparticles (N1), Nylon cloth HDTMS (N2), Nylon cloth − silver nanoparticles − HDTMS (N3), and Nylon cloth HDTMS silver nanoparticles (N4). The silver nanoparticles were performed by using UvVis spectrophotometer, antibacterial activity of Nylon against S.aureus and E.coli was determined by measuring a diameter of clear zone, and water contact angle of the sample was measured by a sessile drop method. Silver nanoparticles are successfully produced using Terminalia catappa extracts as indicated by the absorption peaks at 448.50nm. Samples of Nylon cloth-silver nanoparticles − HDTMS (N3) show the highest antibacterial activity against S. aureus and E. coli with a strength 3 to 13 times greater than silver nanoparticles. Each sample of N1, N2, N3, and N4 shows the same ability to inhibit the growth of S.aureus and E.coli. The addition of HDTMS increases contact angle of nylon cloth.
