Ferrocenyl(benzyl) imidazole (FcIm) and two related methyl‐imidazolium salts (FcMIm⁺I^– and FcMIm⁺PF₆^–) were synthesized for their incorporation into plasticized PVC by solvent casting technique. The obtained materials were investigated for their thermal stability and, compared to pure polymer, films containing ionic ferrocene derivatives in 0.5% w/w loading were found slightly more stable. The pure ferrocene compounds showed antibacterial activity against Staphylococcus epidermis, but not against Escherichia coli, with a maximum for FcMIm⁺PF₆^– salt. After incorporation into PVC polymer, antibacterial activity against S. epidermis was observed (by disk diffusion test) only for PVC/FcMIm⁺PF₆^– (5% w/w) film, from which a release of 14.6% of the ferrocenilimidazolium cation in aqueous medium was measured after 24 hr.

含二茂铁的聚合物材料的制备，表征和抗菌活性

合成了二茂铁（苄基）咪唑（FcIm）和两种相关的甲基咪唑鎓盐（FcMIm ⁺ I ^–和FcMIm ⁺ PF ₆^–），通过溶剂浇铸技术将其掺入增塑的PVC中。对获得的材料的热稳定性进行了研究，与纯聚合物相比，发现以0.5％w / w的载量包含离子二茂铁衍生物的薄膜更加稳定。纯的二茂铁化合物对表皮葡萄球菌具有抗菌活性，但对大肠埃希氏大肠杆菌没有，最大的FcMIm ⁺ PF ₆^–盐。掺入PVC聚合物后，对S的抗菌活性。仅通过PVC / FcMIm ⁺ PF ₆^–（5％w / w）膜观察到了表皮（通过圆盘扩散测试），在24小时后从中测量了在水性介质中14.6％的二茂铁咪唑阳离子的释放。
