Abstract

Nanocomposite polyester fabrics (NCPFs) with in situ generated copper nanoparticles (CuNPs) were prepared using tamarind leaf extract as a reducing agent and different concentrated aq.CusO₄·5H₂O as source solutions. These fabrics were analyzed by SEM, FTIR spectroscopy, XRD, and antibacterial tests. SEM analysis indicated the in situ generation of roughly spherical CuNPs in the size range of 58–154 nm with an average of 90 nm. X-ray analysis indicated the generation of both CuNPs and Cu₂O nanoparticles in the NCPFs. The NCPFs exhibiting antibacterial activity against both the Gram-negative and Gram-positive bacteria can be considered for medical applications.

摘要

以罗望子叶提取物为还原剂，以不同浓度的CusO ₄ ·5H ₂ O水溶液为原料，制备了具有原位生成的铜纳米粒子（CuNPs）的纳米复合聚酯织物（NCPF）。通过SEM，FTIR光谱，XRD和抗菌测试对这些织物进行了分析。SEM分析表明，原位生成的球形CuNPs尺寸范围为58–154 nm，平均90 nm。X射线分析表明在NCPF中同时生成了CuNP和Cu ₂ O纳米粒子。对革兰氏阴性细菌和革兰氏阳性细菌均显示出抗菌活性的NCPF可以考虑用于医疗应用。
