摘    要:系统地研究了不同竹龄、部位毛竹(Phgllochysheterocyclavar.pubscense)化学成分的差异;应用化学光电子能谱仪(ESCA)和红外光谱(FTIR)对竹材的表面性能进行了分析表征。结果表明:不同竹龄竹材抽提物差异较大;竹材从根部到梢部,pH值逐渐增加;从竹青到竹黄,pH值逐渐降低;竹青表面的氧原子大于竹黄表面氧原子的比例;竹材的表面主要以木质素和各种抽提物为主,而纤维素和半纤维素含量明显低于木质素和抽提物;靠近竹青处的竹材表面的半纤维素含量低于竹黄,竹青的表面的羟基震动强于竹黄,且竹青表面的活性自由羟基的数量高于竹黄表面。

关 键 词:竹材  化学成分  表面性能  ESCA分析  FTIR分析

Abstract:Differences of chemical components of bamboo (Phyllostachys heterocycla var. pubscense) of different ages and positions were studied systematically, and surface performances of bamboo wood were characterized using ESCA and FTIR. Result showed that the difference of abstracts from bamboo of different ages is significant. The pH value of bamboo increases from bottom to top and from outside to inside, and the proportion of oxygen atoms on the outer surface of bamboo are higher than that on the inner surface. Lignin and abstracts mainly make up of the surface so that the contents of cellulose and hemicellulose on the surface of bamboo wood are obviously lower than those of lignin and abstracts, and the hemicellulose content in the outer layer of bamboo wood is lower than that in the inner layer. The hydroxide vibrates more intensively in the outer layer, and the amount of active free hydroxide in the inner layer is lower than that in the outer layer.
Keywords:Bamboo wood  Chemical components  Surface performances  ESCA analysis  FTIR analysis
