Abstract

The recent outbreak of Covid-19 has led to great awareness about microbial infections which have emerged as one of the most challenging threats to human life during the pandemic times. While exploring the antibacterial properties in a variety of compounds, quaternary ammonium compounds (QAC) have been recognized as a potential class of antibacterial compounds. In the present study, surface modification of Kosa silk was achieved by graft copolymerization of vinyl benzyl trimethyl ammonium chloride (VBT) by redox polymerization, employing ceric ammonium nitrate (CAN) as an initiator in the presence of nitric acid as catalyst. The grafted silk material was characterized by various analytical techniques like SEM, DSC, FTIR, and XRD. The KS-g-VBT was evaluated for its antibacterial potential by employing S. aureus and E. coli bacteria following the Agar well method. It was observed that the grafted Kosa silk inhibited the growth of Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria.

乙烯苄基三甲氯化铵（VBT）接枝共聚对蚕丝纤维表面的改性及其抗菌性能研究

最近爆发的Covid-19疫情使人们对微生物感染有了极大的认识，微生物感染已成为大流行时期对人类生命最具挑战性的威胁之一。在探索多种化合物的抗菌性能的同时，季铵盐化合物（QAC）已被公认为一类有潜力的抗菌化合物。以硝酸为催化剂，以硝酸铈铵（CAN）为引发剂，氧化还原聚合法接枝乙烯苄基三甲基氯化铵（VBT），对科沙丝进行了表面改性。采用SEM、DSC、FTIR、XRD等分析技术对接枝丝材料进行了表征。采用琼脂孔法对金黄色葡萄球菌和大肠杆菌进行抑菌试验，评价了KS-g-VBT的抑菌潜力。结果表明，嫁接的科沙丝抑制了革兰氏阳性菌（金黄色葡萄球菌）和革兰氏阴性菌（大肠杆菌）的生长。
