23 Jul Preparation method of graphene oxide/konjac glucomannan degradable composite film material
Abstract
The invention discloses a preparation method of a graphene oxide/konjac glucomannan degradable composite film material. The preparation method is characterized by comprising the steps of: preparing graphene oxide aqueous solution with mass percent concentration of 0.01-1%; adding konjac glucomannan in the graphene oxide aqueous solution under stirring according to a proportion that the mass ratio of graphene oxide to konjac glucomannan is 1: 1-200, stirring for 0.5-3 hours at 30-60DEG C, and standing to obtain a film solution; pouring the film solution in a die for manufacturing a film, drying in a drying oven, cooling, and uncovering the film to obtain the composite film; and placing the composite film in glutaraldehyde aqueous solution, reacting for 1-5 hours at 5-60DEG C, taking out, and drying to obtain the graphene oxide/konjac glucomannan degradable composite film material. The material prepared by the method has the advantages of good mechanical property, high heat stability, good degradability and biocompatibility and the like, and can be used as a tissue engineering support material or a package material.
