NOVELTY - The preparation of three-dimensional multi-fold graphene oxide involves adding graphite oxide to deionized water, ultrasonically dispersing to form graphene oxide dispersion, dripping dispersed graphene oxide dispersion onto the substrate of superhydrophobic surface by dropper, and placing entire substrate in an oven for drying. USE - Preparation of three-dimensional multi-fold graphene oxide. ADVANTAGE - The method enables preparation of high water absorption three-dimensional high-density multi-pleated graphene oxide with strong practicability and wide application prospect by simple, economical and environmentally-friendly process.
