Description

technical field

[0001] The invention relates to a konjac glucomannan hydrogel, and also relates to a preparation method of the hydrogel, which is widely used in biochemistry, medicine, agriculture and daily chemical industry. Background technique

[0002] Polymer hydrogel is a body-shaped network of hydrophilic polymers that can swell in water and retain a large amount of water without dissolving. Hydrogels have many applications in the fields of biochemistry, medicine, agriculture, and daily chemical industry. So far, most hydrogels are non-biodegradable, which limits their applications in medicine and environmental protection.

[0003] Konjac belongs to the Araceae plant, and its tubers are rich in reserve polysaccharide konjac glucomannan. Konjac glucomannan is the main component of konjac fine powder, accounting for about 50%-60% of the dry product weight. As a natural polymer polysaccharide, konjac glucomannan has many good properties, su...
