In the current study the bamboo rayon fabric grafted with acrylamide was utilized as a backbone to immobilize copper nanoprticles. The grafted bamboo rayon was first treated with CuSO4 followed by chemical reduction. The modified product was characterized using FTIR, TGA and SEM. The characteristic color developed after reduction was measured spectrophotometrically. The grafted bamboo rayon with Cu nanoparticles 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 bacterias which was found to be durable till 50 washes. The material can be claimed as suitable candidate for medical textile applications to prevent cross-infections.
在本研究中,利用丙烯酰胺接枝竹原纤维作为载体固定铜纳米粒子。首先用 CuSO4 对接枝竹原纤维进行预处理,然后进行化学还原。采用 FTIR、TGA 和 SEM 对改性产物进行了表征。还原后形成的特征颜色通过分光光度法进行测量。然后评估了负载 Cu 纳米粒子的接枝竹原纤维对革兰氏阳性菌和革兰氏阴性菌的抗菌活性以及洗涤后的抗菌耐久性。该产品对两种类型的细菌均表现出抗菌活性,并且在经过 50 次洗涤后仍具有耐久性。该材料可作为医用纺织品应用的合适候选物,以防止交叉感染。
