摘要: 探索了微粉化过程对各种纤维素材料超分子结构的影响.结果表明,稀盐酸水解制得的微粉(和微晶)纤维素,在结晶状态(如聚合度、结晶度、晶粒尺寸等)及晶粒聚集体的形态结构上,均随纤维素晶型的不同而变,并与硫酸水解和机械微粉化不同.X-射线衍射分析显示:微粉化产物仍保持其纤维素材料原来的晶型和两相(晶区与非晶区)共存的微细结构.

Abstract: The production of micronized cellulose by acid hydrolysis induced the changes inmain structural characteristics,such as degree of polymerization, crystallinity,size of crys-tallites and morphological structure,which depend greatly on the original crystalline typesand means of the treatment.The results from X-ray diffraction showed that the biphase sys-tem still remains in the micronized celluloses,so their original crystalline type.

Key words: micronized cellulose, microcrystalline cellulose, polymerization degree, crystallinity, crystalline type, structural morphology
