He evens adds in some base ammonia to ensure that everything is deprotonated. Adding salt or other electrolytes to the solution or even lowering the pH results in aggregation, further confirming that the unstabilized charges are necessary for aggregate prevention. Then, Wallace goes a little crazy. The authors don't claim that this material will cure cancer, AIDS, poverty, hunger, and global warming; but let's just say they didn't explicitly rule any those out.
Then they discuss putting the graphene-ish material onto surfaces, through drop-casting, air-brushing, and layer-by-layer assembly. To their credit, they get some supposedly nice films of graphene in these ways, but they go a little overboard describing the anti-static coatings, FETs, sensors, supercapacitors, and membranes that future generations will make with their materials.
All in all, a decent paper that describes a small but quite important step in furthering graphite oxide-derived graphene science. Li, D. Processable aqueous dispersions of graphene nanosheets.

TEM image from Mr.Li, Dan, et al.. The direct dispersion of hydrophobic graphite or graphene sheets in water without the assistance of dispersing agents has generally been considered to be an insurmountable challenge.
Herein, we report two complementary methods for enhancing the dispersibility of amphiphilic 24 graphene oxide sheets in aqueous electrolyte solutions Figure 1.
Two complementary strategies, utilizing either electrostatic or steric stabilization, have been developed to enhance the stability of graphene oxide in electrolyte solutions, allowing it to stay dispersed in cell culture media and serum. The theoretical Pasadena, CA: Unidym, Inc.
