用X-射线衍射和红外光谱研究了珍珠棉纤维素晶体结构随树龄的变化。随着树龄的增加，结晶度和晶体尺寸所占比例逐渐增加。FT-IR光谱表明，Nalita纤维素为单斜晶胞结构（I β）。30月龄的娜丽塔木材的结晶度和晶体尺寸的比例高于白杨木材。还研究了不同龄期Nalita纤维素的聚合度。纤维素聚合度随树龄的增加而增加。Nalita纤维素的聚合度低于白杨纤维素。葡萄糖含量随树龄的增加而增加。
The change of crystalline structure of Nalita cellulose with tree age has been studied using X-ray diffraction and FT-IR spectroscopy. The proportion of crystallinity and crystal size were increased with tree age. FT-IR spectroscopy showed that the Nalita cellulose was a monoclinic unit cell structure (Iβ). The proportion of crystallinity and crystal size of the 30-month-old Nalita wood was higher as compared to aspen wood. The degree of polymerization (DP) of Nalita cellulose of different ages has also been studied. The DP of cellulose increased with tree age. The DP of Nalita cellulose was lower than that of aspen cellulose. The percentage of glucose in Nalita wood increased with tree age.
