Figure 3From: Facile synthesis and strongly microstructure-dependent electrochemical properties of graphene/manganese dioxide composites for supercapacitorsTEM micrographs of the graphene/MnO 2 composites. From top to bottom, the images correspond respectively to 5-, 10-, and 15-min microwave reaction times. The left panels (a, c, e) are low-magnification images and the right panels (b, d, f) are high-magnification TEM images of the composites.Back to article page
