THE INFLUENCE OF PLASMA TREATMENT ON ADHESIVE QUALITY OF SILVER NANOPARTICLES

Textile materials have high porosity, high interior surface, along with high strength and structure flexibility therefore they are important from technical point of view. Textile materials are ideal carriers of nanoparticles whereas catalytic or barrier effect of these nanoparticels can be synergic advanced. The immobilization and fixation of this on textile surface are the main problems in application. Plasma technology performed under atmospheric pressure is used to modify the chemical structure and also topography of the surface of the material. Fields of application can be: desizing, funcionalizing, and design of surface properties of textile fibers. Dielectric barrier discharge is broadly used for atmospheric pressure treatment of large movable materials. Surfaces of textile fibers can be modify with dielectric barrier discharge without modifying the bulk properties. The influence of plasma treatment on sorption of silver nanoparticles from liquid on textile was tested in this study. The samples were treated by diffuse coplanar surface barrier plasma discharge (DCSBD). Changes in chemical structure were observed by FT-IR. Nanoparticles were applied on surface from the solution. The antibacterial effect of silver was tested against Escherichia coli. The surface of fibres with nanoparticles was observed by scanning electron microscope (SEM).
