摘要

提出了一种以离子液体稳定银纳米粒子(SNP)为基材制备分段聚氨酯抗菌涂料的新方法。利用x射线散射、电子显微镜、红外光谱、差示扫描量热法和琼脂扩散微生物法研究了银纳米颗粒对所得材料结构和特性的影响。结果表明，在聚合物基体中形成了7 ~ 19 nm大小的SNPs，其大小与稳定剂的含量有关。所获得的纳米复合涂层对细菌(金黄色葡萄球菌、大肠杆菌)和真菌(白色念珠菌)具有较高的抗菌活性。

Obtaining, Structure, and Antimicrobial Properties of Nanocomposite Coatings Based on Polyurethane and Silver Nanoparticles

A new method of obtaining of antimicrobial coatings based on segmented polyurethanes and silver nanoparticles (SNP) stabilized by an ionic liquid is proposed. The effect of silver nanoparticles on the structure and characteristics of the obtained materials have been studied using X-ray scattering, electron microscopy, infrared spectroscopy, differential scanning calorimetry, and the microbiological method of diffusion in agar. It is established that in the polymer matrix, SNPs with sizes from 7 to 19 nm are formed, and their size depends on the content of the stabilizer. The obtained nanocomposite coatings exhibit high antimicrobial activity against bacteria (S. aureus, E. coli) and fungi (C. albicans).
