摘要: Abstract Graphene oxide (GO) nanosheets of planar flake-like structures are fabricated by using a modified Hummers method. Fractal theory is introduced to characterize the topological surfaces and porous GO nanosheets, fractal dimensions estimated box-counting method close 2, indicating that possess perfectly smooth surfaces, which agrees well with high resolution transmission electron microscopy (HRTEM) images, higher dimension 2.74 determined Frenkel-Halsey-Hill (FHH) model suggests wealth microporous nanosheets.
