Abstract

A novel N-halamine-based cyclic polysiloxane compound (KCNCTSi) was synthesized and used as an antibacterial agent on cotton fabric. The structures were characterized by Fourier transform infrared spectra (FTIR). The surface morphology of treated cotton fabrics was tested by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The treated cotton fabrics were tested by thermogravimetric analysis (TGA) and showed good thermal stability. The treated cotton fabrics after chlorination exhibited strong antibacterial efficiency against Gram-positive bacteria S. aureus and Gram-negative bacteria E. coli. The E. coli antibacterial rate was about 98.35 % and the S. aureus antibacterial rate was about 99.51 %. The inhibition zones were 1 mm and 1.5 mm against E. coli and S. aureus when KCNCTSi concentration was 350 g/l. The mechanical properties and whiteness were also investigated. As a result of the performed modifications, cotton fabrics with high antibacterial property were obtained.

新型N-卤胺基环状聚硅氧烷的合成及其在棉织物上的抗菌应用

摘要

合成了一种新型的N-卤胺基环状聚硅氧烷化合物（KCNCTSi），并将其用作棉织物上的抗菌剂。通过傅立叶变换红外光谱（FTIR）对结构进行了表征。经处理的棉织物的表面形态通过扫描电子显微镜（SEM）和能量色散谱仪（EDS）进行测试。经处理的棉织物通过热重分析（TGA）进行测试，并显示出良好的热稳定性。氯化后处理过的棉织物对革兰氏阳性菌金黄色葡萄球菌和革兰氏阴性菌大肠杆菌表现出很强的抗菌作用。的大肠杆菌的抗菌率约为98.35％，而金黄色葡萄球菌抗菌率约为99.51％。当KCNCTSi浓度为350 g / l时，对大肠杆菌和金黄色葡萄球菌的抑制区分别为1 mm和1.5 mm 。还研究了机械性能和白度。进行改性的结果，获得了具有高抗菌性能的棉织物。
