Title: Investigation on dielectric barrier discharge surface functionalization by XPS-analysis
Keywords: Dielectric barrier discharge surface treatment, plasma aided capillary impregnation, flame retardation of cellulosic fibrous materials, x-ray photoelectron spectroscopy

Abstract: The plasma aided flame retardation of wood, wooden products and cellulosic fibrous materials has been conceived and developed as a result of a plasma aided process of capillary impregnation. The dielectric barrier discharge surface pre-treatment modifies the chemical and capillary activity and improves such characteristics of the impregnation process as the penetration depth, speed of solution spreading and adsorption, and capacity of adsorbed solution. The effect of plasma pre-treatment onto the wood surface activation (or functionalization) was investigated on Tzalam wood (Lysiloma bahamensis). The alteration of the wood surface chemical composition or the surface functionalization as a result of the cold plasma pre-treatment at atmospheric pressure and room temperature was monitored by X-ray photoelectron spectroscopy (XPS -analysis, ESCA).
