摘要

采用化学分析光电子能谱（ESCA）研究了杉木和杨木在乙酰化处理前后的表面化学结构变化。结果表明 :杉木和杨木的表面化学特征有很大差别 ,杉木表面的碳原子相对含量较杨木表面高 ,而氮原子和氧原子的相对含量较杨木表面低。在杨木表面有钙原子的存在 ;两种木材经乙酰化处理后表面化学特征发生变化 ,非极性的 O- C=O结构相对含量均有不同程度的增加。

Abstract

Surface chemical construction changes of Chinese Fir ( Cunninghamia lanceolata ) and Poplar "Sanbei No.1"( Populus nigra×P.simonii ) treated with acetyloide were studied by using ESCA analysis. The results showed that there were great differences of surface chemical characteristics between Chinese Fir and Poplar. In the surface of Chinese Fir, the ratio of carbon atom was higher than that in Poplar, but the ratio of nitrogen atom and oxygen atom was lower than that in Poplar. Furthermore, there was calcium atom in the surface of Poplar. After reaction with acetyloide, the surface chemical characteristics of wood had been changed ; the ratio of O-C=O structure (carbon of carboxyl and ester) was increased.
