Abstract
Superhydrophilic copper surfaces with hierarchical textures have exhibited a high efficiency in fighting against nosocomial infections. However, one of the key drawbacks of these surfaces is their high susceptibility to mechanical contamination with fibrous materials in the course of sanitation procedures. This study has proposed a method for a laser modification enhancing the resistance of superhydrophilic copper surfaces to fiber contamination during their sanitary treatment. The modified surfaces retain their superhydrophilicity and exhibit superhydrophobic properties after the application of a hydrophobic agent. Moreover, the proposed modification method improves the resistance of a hierarchical texture to abrasive wear while remaining preserved high bactericidal properties. The results obtained have suggested that these modified textured copper materials can be used as bactericidal contact surfaces to combat nosocomial infections in medical facilities.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
