Abstract

Abstract:

Electron Spin Resonance (ESR) and X-ray Photoelectron Spectroscopy (XPS) were used to determine the surface properties of untreated/treated wood in this paper. The spectra of ESR showed that a great deal of free radicals on (Alnus nepalensis ) surface could be generated by MWP treatment; XPS spectra showed that: microwave plasma treatment increased the O/C atomic ratio of the wood surface, decreased C₁, increased C₂ and C₃, and generated C₄ These results suggesting that a great deal of oxygen content groups or peroxides were generated on wood surface after MWP treatment.

Key words: Microwave plasma, Wood surface, ESR, XPS
