“…By searching the literature, we found that many other nanoparticles produced wrinkles on GO as well. 13,[30][31][32][33][34] Our own experiment also indicated that silica nanoparticles can produce very obvious wrinkling ( Figure S2A). On the other hand, if GO is dried by itself, no extensive wrinkling was observed ( Figure 2F).…”

With the thickness of only a single atomic layer, graphene displays many interesting surface properties. A general observation is that wrinkles are formed on graphene oxide (GO) when it is dried in the presence of adsorbed inorganic nanoparticles. In this case, evaporation induced wrinkling is not an elastic deformation but is permanent. Understanding the nanoscale force of wrinkle formation is important for device fabrication and sensing. Herein, we employ surface functionalized gold nanoparticles (AuNPs) as a model system. All tested AuNPs induced wrinkling, including those capped by DNA, polymers and proteins. The size of AuNPs is less important compared to the property of solvent. Wrinkle formation is attributed to drying related capillary force acting on the GO surface, and a quantitative equation is derived. After drying, the adsorption affinity between GO and AuNPs is increased due to increased contact area.

“…Inorganic nanoparticles can assemble on the CMG surfaces as particle nucleated/anchored on CMG substrates, with different characters and morphologies, resulting in hybrid structures with unique features inherited not only from the individual components but also emerged from the synergistic coupling of their components 96, 97, 98, 99, 100. The inherent properties of graphene or chemically modified graphene make it a suitable substrate for nanomaterials in many various applications 101, 102.…”

Due to unique planar structures and remarkable thermal, electronic, and mechanical properties, chemically modified graphenes (CMGs) such as graphene oxides, reduced graphene oxides, and the related derivatives are recognized as the attractive building blocks for “bottom‐up” nanotechnology, while self‐assembly of CMGs has emerged as one of the most promising approaches to construct advanced functional materials/systems based on graphene. By virtue of a variety of noncovalent forces like hydrogen bonding, van der Waals interaction, metal‐to‐ligand bonds, electrostatic attraction, hydrophobic–hydrophilic interactions, and π–π interactions, the CMGs bearing various functional groups are highly desirable for the assemblies with themselves and a variety of organic and/or inorganic species which can yield various hierarchical nanostructures and macroscopic composites endowed with unique structures, properties, and functions for widespread technological applications such as electronics, optoelectronics, electrocatalysis/photocatalysis, environment, and energy storage and conversion. In this review, significant recent advances concerning the self‐assembly of CMGs are summarized, and the broad applications of self‐assembled graphene‐based materials as well as some future opportunities and challenges in this vibrant area are elucidated.

“…AuNPs can be decorated to GO surface based on NH-Au binding [108] or SH-Au binding [109]. DNA [110] and proteins [111] have been also used as the molecular linkers between AuNPs and GO. These methods have greatly increased the uniformity and density of AuNPs.…”
