Impact of air-plasma treatment at atmospheric pressure on wood and wood extractives
Abstract
This study addresses the question of whether the extractives or the main components of wood are responsible for the alterations in surface energy after air-plasma treatment. For this purpose, x-ray photoelectron spectroscopy was carried out on untreated, microtomed and air-plasma-modified beech wood surfaces. A dielectric barrier discharge at atmospheric pressure was used for plasma modification. The results indicate that air-plasma treatment affects the O/C-ratio and surface energy characteristics of wood surfaces by oxidative alteration and exposition of the wood main components.
