Abstract

Chitin nanocrystals and microfibrils were prepared based on the strong acid hydrolysis method. The change in the molecular structure was studied by Fourier-transform infrared and Raman spectroscopy. The surface morphology of chitin materials was observed using scanning electron and optical microscopy. The separation of nano-crystals and microfibril crystalline regions from native chitin may increase the scope of its application for the creation of bioactive composites and scaffolds for tissue culture. As a result of the conducted experimental work, it was possible to loosen the amorphous areas and partially separate nano-crystals and chitin microfibrils. Stable aqueous suspensions of chitin nano-crystals and microfibrils were obtained, which can be used for further experimental work.

纳米晶体和甲壳素微纤维的制备

采用强酸水解法制备了甲壳素纳米晶和微纤维。通过傅立叶变换红外光谱和拉曼光谱研究了分子结构的变化。用扫描电子显微镜和光学显微镜观察了甲壳素材料的表面形貌。从天然几丁质中分离纳米晶体和微纤维结晶区域可以扩大其在创建生物活性复合材料和组织培养支架方面的应用范围。作为所进行的实验工作的结果，可以使无定形区域变松，并部分分离纳米晶体和甲壳素微纤维。获得了稳定的甲壳素纳米晶体和微纤维的水悬浮液，可用于进一步的实验工作。
