摘要
在多相体系下对微晶纤维素进行了表面改性,得到了只改善表面物性而不破坏其内部结晶区结构的微晶纤维素,同时其分散性和与高分子体系的相容性也有一定改善。通过一系列的表面改性,研究了微晶纤维素的晶体结构和物性随着取代度的变化规律,并利用TGA对其热性能进行了分析。
The aim of surface modification of microcrystalline cellulose (MCC) is to improve its surface physiochemical properties and to prompt its compatibility with lipophilic materials. The series experiments have been done in order to study the influence on the products′ properties with different dosages of acetic anhydride. The crystallinity and thermal properties of MCCs by surface modified were analyzed by X-ray and TGA.
