Title: INVESTIGATION ON PLASMA AIDED FLAME RETARDATION OF TZALAM WOOD (LYSILOMA BAHAMENSIS) BY XPS-ANALYSIS
Keywords: DIELECTRIC BARRIER DISCHARGE PRE-TREATMENT, FLAME RETARDATION OF CELLULOSIC FIBROUS MATERIALS, PLASMA AIDED CAPILLARY IMPREGNATION, 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 activity of wood 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-aided capillary impregnation with phosphor and nitrogen containing flame retardants onto the wood surface functionalization was investigated and monitored on Tzalam wood (Yucatan, Mexico) by X-ray photoelectron spectroscopy (XPS-analysis, ESCA).
