NOVELTY - The method involves taking straw fiber as main raw material to remove stalk of pulp after drying at 100 degrees C, and grinding to small size. The graphene oxide is placed in deionized water under ultrasonic dispersion for 2-4 hours to obtain homogeneous dispersion concentration of graphene oxide aqueous solution. The composite material is mechanically stirred to the mixture at 80 degrees C-90 degrees C, the mixture is allowed viscous dry for 12 hours at 50 degrees C-60 degrees C, and the graphene oxide coated straw powder is obtained. USE - Oxidation graphene retardant combustion straw material preparation method. ADVANTAGE - The oxidation graphene retardant combustion straw material preparation is performed in simple and environmental friendly manner.
