硫脲壳聚糖/蒙脱土纳米中间体的合成及其对大肠杆菌抑菌性能的研究

Preparation and antibacterial activity against E.coil of thiourea chitosan/montmorillonite nanocomposites

通过插层技术合成了硫脲壳聚糖/蒙脱土(Cts-TU/MMT)纳米中间体,利用XRD和FT-IR对合成的硫脲壳聚糖/蒙脱土纳米中间体进行了表征,结果表明硫脲壳聚糖已经进入了蒙脱土层间,其层间距达到3.529nm;通过抑菌动力学实验评价了硫脲壳聚糖/蒙脱土纳米中间体对大肠杆菌的抑菌性能,预示了其在生物医药领域的潜在应用性。

In this research,a novel nanocomposite thiourea chitosan/montmorillonite（Cts-TU/MMT） was prepared through solution intercalated reaction.The properties of this nanocomposites were characterized by X-ray diffraction（XRD） and Fourier transformed infrared（FT-IR）.The results showed that Cts-TU had intercalated into MMT.The basal spacing of montmorillonite is high to 3.529nm.Evaluation of Cts-TU/MMT nanocompo-sites by inhibitory kinetics test indicates its potential candidates for various applications in medical field.
