The invention provides methods and materials for decontamination of surfaces and fabrics, such as non-woven fabrics, that are contaminated with infestations of microorganisms such as bacteria. Biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group can be used to decontaminate infested surfaces in the presence of oxygen and, optionally, illumination. Fibers incorporating biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group, wherein the oligomer is physically associated with or covalently bonded to, or both, the fiber-forming polymer can be used to form non-woven mats. Biocidal non-woven mats prepared by methods of the invention, incorporating the biocidal oligomers, can be used to suppress bacterial growth in wound and surgical dressings and personal hygiene products.
本发明提供了用于净化被细菌等微生物侵染的表面和织物(如无纺布)的方法和材料。具有共轭低聚(芳基/异芳基乙炔基)结构并包含至少一个阳离子基团的杀菌低聚物可用于在有氧和可选照明的情况下净化受侵染的表面。含有具有共轭低聚-(芳基/异芳基乙炔基)结构并包含至少一个阳离子基团的杀菌低聚物的纤维,其中低聚物与成纤聚合物物理连接或共价键合,或两者兼有,可用于形成无纺毡。通过本发明的方法制备的含有杀菌低聚物的杀菌无纺布垫可用于抑制伤口和手术敷料以及个人卫生用品中的细菌生长。
