| Autors: Dineff, P. D., Ivanov, I. G., Gospodinova, D. N. Title: Plasma-aided capillary impregnation for flame retardancy of wood I. Surfactants-assisted capillary impregnation Keywords: dielectric barrier air discharge (DBD), plasma-aided capilla Abstract: The plasma aided flame retardation of wood and wooden products has been conceived and developed as a result of plasma aided process of capillary impregnation. The plasma-chemical surface pre-treatment in air at atmospheric pressure substantially alters its electrical, chemical and capillary activity, thus improving some basic characteristics of the impregnation process, such as penetration depth, solution spreading and adsorption speed, adsorbed solution capacity. Sessile drop technique has been used to reveal the impact of an anionic aqueous surfactant on plasma-aided capillary impregnation of three rain-forest woods - Mexican white cedar (Cupressus Lusitanica), Mahogany Caoba (Swietenia macrophylla), and Tzalam (Lysiloma Bahamensis).
