specific Embodiment approach 1

[0036] Specific embodiment one: the preparation method of a kind of chitin nanofibril provided in this embodiment, specifically is finished according to the following steps:

[0037] 1. Drying and pulverizing the biological raw material to obtain biological raw material powder; or directly pulverizing to obtain biological raw material powder, wherein the biological raw material is the exoskeleton of a crustacean containing chitin;

[0038] 2. Add lye to the biological raw material powder obtained in step 1 for processing, and obtain the biological raw material powder with partial protein removal;

[0039] 3. Add hydrochloric acid solution to the biological raw material powder obtained in step 2 to obtain demineralized salt and partial protein biological raw material powder;

[0040] Four, add lye to the biological raw material powder of demineralized salt and part protein obtained in step 3 and carry out further processing, obtain the biological raw material powder of deminera...

specific Embodiment approach 2

[0053] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the biological raw material described in step 1 is shrimp shell or crab shell, and the particle size of the biological raw material powder is 50 mesh to 70 mesh. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0054] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the drying described in step 1 is drying at 50° C. to 105° C. for 10 minutes to 180 minutes. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for preparing chitin nano filaments, relates to the method for preparing the nano filaments and solves the problems that the chitin nano filaments prepared by the conventional method for preparing the chitin nano filaments are short and cannot meet the market demand. The method for preparing the chitin nano filaments comprises the following steps of: 1, pretreating biological raw materials; 2, partially deproteinizing; 3, removing mineral salt; 4, further deproteinizing; 5, degreasing; 6, removing pigments; 7, preparing nano filament dispersion liquid; and 8, preparing the chitin nano filaments. A product prepared by the method for preparing the chitin nano filaments can be applied to the fields of biological medicine, tissue engineering, optical devices and nano templates.

Description

technical field [0001] The invention relates to a preparation method of nano fibrils. Background technique [0002] Chitin is a natural polysaccharide polymer, its natural annual output is second only to cellulose, as high as 10 10 -10 11 Ton. In nature, chitin widely exists in the cells of lower plant fungi and algae, the shells of arthropod shrimp, crabs, insects, shellfish, molluscs (squid, cuttlefish) and cartilage. Natural chitin is a semi-crystalline biopolymer in the form of microfibrils. Although it has excellent material properties, most crab shells and shrimp skins are discarded as industrial waste, and these biomass raw materials have not been efficiently utilized. Therefore, there is an urgent need to process such biomass resources and develop new materials as natural and environmentally friendly raw materials. [0003] Chitin is a linear aminoglycan, which is (1,4)-β-N polyacetamide glucose, and each structural unit contains two hydroxyl groups and one aceta...
