NOVELTY - Preparing elastic composite involves adding glucomannan of konjac into a graphene oxide and aqueous solution in mass percentage concentration of 0.01-0.1 wt.%, stirring for 0.5-1 hours and sonicating for 1-2 hours to obtain konjac glucomannan and graphene oxide mixed solution. The graphene oxide and konjac glucomannan mass ratio of 1:10-100, and mixed solution is placed in a refrigerator at 0-4 degrees C for 0.5-1 hour, pre-cooled and placed in an ice-mold freezer device to freeze the mixed solution of konjac glucomannan and graphene oxide solidified into a frozen to obtain freeze-dried mixture. USE - Method for preparing elastic composite (claimed). ADVANTAGE - The method enables to prepare elastic composite, which has good compressive resilience and natural degradation, and widely applied to field of liquid filtration, purification and separation, sound absorption and vibration reduction, cosmetics and packaging materials. DETAILED DESCRIPTION - Preparing elastic composite involves adding glucomannan of konjac into a graphene oxide and aqueous solution in mass percentage concentration of 0.01-0.1 wt.%, stirring for 0.5-1 hours and sonicating for 1-2 hours to obtain konjac glucomannan and graphene oxide mixed solution. The graphene oxide and konjac glucomannan mass ratio of 1:10-100, and mixed solution is placed in a refrigerator at 0-4 degrees C for 0.5-1 hour, pre-cooled and placed in an ice-mold freezer device to freeze the mixed solution of konjac glucomannan and graphene oxide solidified into a frozen to obtain freeze-dried mixture. The obtained freeze-dried mixture is dried for 2-3 days to prepare a konjak glucomannan and graphene oxide sponge dried body. The konjac glucomannan and graphene oxide sponge dried are placed in a mass concentration of 0.56-2.8 wt.% alkali solution, and reaction is carried out by using hydrothermal process, and then rinsed with deionized water to a neutral, freeze-dried for 2-3 days to obtain the desired product.
