STUDY OF GRAFTED SILVER NANOPARTICLE CONTAINING DURABLE ANTIBACTERIAL BAMBOO RAYON

摘要

In the current study, the bamboo rayon fabric was grafted with acrylic acid using potassium persulfate as an initiator and further treated with silver nitrate followed by borohydride reduction. The modified product was characterized using FTIR, TGA and SEM. The characteristic brown colour developed after reduction was measured spectrophotometrically. The grafted bamboo rayon with nanosilver was then evaluated for antibacterial activity against both gram-positive and gram-negative bacteria and the durability of their antibacterial activity after washing. The product showed antibacterial activity against both types of bacteria, which was found to be durable until 50 washes.
