【摘要】 利用固体核磁共振研究天然高分子纤维素及其复合材料的聚集态结构和分子运动。通过氢谱,碳谱,变温谱,弛豫时间等多种方法对材料进行多层次的研究。以纤维素/聚己内酯为例,阐述纤维素对聚己内酯的增强机理。更多还原

【Abstract】 In this work, solid state nuclear magnetic resonance(NMR) method is used to study the aggregation structure and molecular dynamics properties of Cellulose and composites. As an example, Cellulose Gel/Poly(ε-Caprolactone) composites was studied by 1 H NMR, 13 C NMR and relaxation time measurements were performed to explain the super enhancement effect of cellulose on poly(ε-Caprolactone).更多还原
