Nanocomposite Cotton Fabrics with In Situ Formed Gold Nanoparticles Using Citrus Lemon Leaf Extract as Reducing Agent

ABSTRACT

Using citrus lemon leaf extract and different concentrated gold chloride source solutions, the gold nanoparticles (AuNPs) were in situ formed in cotton fabrics. The nanocomposite cotton fabrics (NCCFs) were analyzed by SEM, FTIR spectroscopy, X-ray, thermal and antibacterial tests. The AuNPs formed in NCCFs were with size between 50 and 120 nm. The x- ray test indicated the formation of AuNPs. The thermal properties of NCCFs were slightly lower than the matrix. The NCCFs showed good antibacterial activity against Gram positive and Gram negative and hence can be considered for potential antibacterial medical fabrics for hospital bed materials, aprons, face/nose masks, etc.

摘要

使用柑橘柠檬叶提取物和不同浓度的氯化金源溶液，在棉织物中原位形成金纳米颗粒. 通过SEM、FTIR光谱、X射线衍射、热分析和抗菌测试对纳米复合棉织物进行了分析. 在NCCFs中形成的AuNP的尺寸在50-120 nm之间. X射线测试表明形成了AuNP. NCCF的热性能略低于基体. NCCFs对革兰氏阳性菌和革兰氏阴性菌表现出良好的抗菌活性，因此可以考虑作为医院床上用品、围裙、面罩/口罩等的潜在抗菌医用织物.
