Provided is a polymer-based antimicrobial composition that is non-toxic, water soluble, and that mitigates the transmission of infectious diseases from surfaces. The composition comprises a cationic polymer, at least one adhesion promoter, optionally organic and/or inorganic particles that are photocatalytically active in visible light, and a carrier, in which the components of the composition are not covalently bound to one another. Also provided is an antimicrobial composition that comprises at least (i) a polyethylenimine-based polymer and a carrier or (ii) an organic and/or inorganic particle that is photocatalytically active in visible light, an adhesion promoter, and a carrier. The antimicrobial compositions can be applied to disinfect a surface and to form residual self-sanitizing films on the surface that are removable.
本发明提供了一种聚合物基抗菌组合物,它无毒、可溶于
水,并能减少传染病从表面的传播。该组合物由阳离子聚合物、至少一种附着力
促进剂、在可见光下具有光催化活性的有机和/或无机颗粒以及载体组成,其中组合物的各组分之间没有共价结合。还提供了一种抗菌组合物,它至少包含(i)聚
乙烯亚胺基聚合物和载体,或(ii)在可见光下具有光催化活性的有机和/或无机颗粒、粘附
促进剂和载体。抗菌组合物可用于表面消毒,并在表面形成可去除的残留自消毒膜。
