Title: Investigation on dielectric barrier discharge surface activation effects
Keywords: flame retardation, cellulosic fibrous materials, XPS, TGA, DTA and DSC

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. X-ray photoelectron spectroscopy (XPS) was applied to study the changed surface composition after plasma pre-treatment. The surface compositions of solid wood products, paper and board are critical to their end use performance. XPS is a powerful non-destructive surface analytical technique which provides valuable data on chemical surface composition and surface reorganization after plasma-chemical pre-treatment. The binding energy as a main characteristic of the atoms was used for elemental identification.
