摘要
采用电子顺磁共振波谱 (ESR)和X射线光电子能谱 (XPS)技术 ,分析了微波等离子体处理前后西南桤木木材表面的性质。ESR图谱分析表明 :经过微波等离子体处理后 ,木材表面可迅速有效地产生大量的自由基 ;XPS图谱分析表明 :微波等离子体处理使木材表面O C原子比增加 ,C1 含量降低 ,而C2 、C3含量增加 ,并有C4 的出现。
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 C 1, increased C 2 and C 3, and generated C 4 These results suggesting that a great deal of oxygen content groups or peroxides were generated on wood surface after MWP treatment.
