Graphite oxide sheets, now called graphene oxide (GO), are made by exfoliation of graphite using century-old chemical reactions. Interest in this old material has resurged with the rapid development of graphene since 2004, as GO is considered to be a promising precursor for bulk production of graphene. Apart from making graphene, GO itself also has many intriguing properties. For example, GO can be viewed as a two-dimensional (2D) soft material such as polymer, highly anisotropic colloid that can form liquid crystals, membrane, or 2D surfactant. In this talk, some curiosity driven discoveries will be shared such as the use of GO as surfactant to process insoluble materials in water. GO sheets are also 2D building blocks to construct massive arrays of 2D nanofluidic channels with high ionic conductivity. Next, a few problems associated with the manufacturing and processing of GO and its graphene product will be discussed, such as the difficulties of imaging these single atomic layers and their ease of aggregation during processing. Strategies and solutions to address these problems will be introduced.
