NOVELTY - The preparation method of graphene oxide modified silicon dioxide aerogel fiber product involves mixing silicon source, alcohol, water and acid catalyst, controlling the pH value of the mixed solution to 2-6 and stirring to obtain silica sol, then adding deionized water and alkali catalyst, controlling the pH value of the mixed solution to 7-11 and stirring to obtain modified sol (A), adding graphene oxide solution to the modified sol (A) to obtain modified sol (B), placing the fiber product in the modified sol (B) to obtain gel, carrying out aging treatment of mixed solution of silicon source/alcohol gel to obtain graphene oxide modified silicon dioxide aerogel/fiber product semi-finished product, and carrying out hydrophobic modification and drying. USE - The method is useful for preparing graphene oxide modified silicon dioxide aerogel fiber product. ADVANTAGE - The method enables convenient preparation of graphene oxide modified silicon dioxide aerogel fiber product with excellent hydrophilic and hydrophobic performance.
