A team of scientists have developed a GO dough that aims to revolutionize the graphene manufacturing industry. This material is kneadable, moldable, and easy to use without problems associated with handling graphene oxide. ( Northwestern University )
The scientist team turned the graphene oxide into a dough and moldable dough that could be used to make free and three-dimensional structures.
This product, called GO dough, promises to solve problems related to the manufacture, storage, delivery and use of graphene. The team's goal is to turn oxidized graphene into a widely accessible engineering material.
A paper on GO dough was published in the journal. Natural communication.
How to make dough they made
Jiaxing Huang, a researcher at Northwestern University, made GO dough by "adding ultra-high concentrations of graphene oxide to water." They can be made into a paste using a binder such as a plastic, but the material must be reworked to remove the additives and return the oxidized graphene to its pure form.
With water they could make the graphene oxide into moldable dough. Adding more water will transform the dough into a high quality GO dispersion.
"At present, oxidized graphene is stored in dry solid or powder form, which is prone to combustion and explosion." Or they should be converted to dilute dispersion which increases the mass of the material by hundreds or thousands of times. "
According to the researchers, when converted to a three-dimensional structure, the GO dough can be converted to "electrically conductive, chemically stable and mechanically rigid" dense solids. The GO dough can also be processed into different types of graphene materials with adjustable microstructures.
Graphene Play Dough for Engineers
Huang and his team believe that the ease of use provided by the GO dough allows the manufacturer to realize the potential to become a superstructure. Graphene oxide is used to make graphene, the thinnest substance known to man, but about 200 times stronger than iron. Graphene is an excellent conductor and light absorbing, making it ideal for electronics and energy storage.
"My dream is to convert graphene-based sheets into easy-to-access and easy-to-use engineering materials like plastics, glass and steel." How GOs can stimulate young children's imagination and creativity I hope that the dough will inspire new uses for graphene-based materials. "
