På väg mot en graphene-baserad genomskinlig ytbeläggning

Graphene is a relatively new material which has had a lot of publicity recently as a group of scientist was rewarded the Nobel Prize in physics for a comprehensive work about single layer graphene in 2010. After the Nobel Prize many people got up their eyes for the subject and that the numbers of rapports have increased from around 500 in 2006 to 3000 in 2010. An ideal sheet of graphene consists of a two-dimensional honeycomb structure of coal atoms in a single layer, the sheet is entirely sp-2 hybridized. To be considered to be graphene the structure can have no more than ten layers. Graphite and graphene shares many similarities between each other and a frequent expression is that graphene is just one layer of graphite. In this study, a new chemical process is used and robust solution process has been developed to obtain high quality graphene sheets in aqueous solution and these sheets were characterized by XRD, FTIR, TGA, UV-Vis, Raman, AFM, TEM and XPS. Graphene sheets developed in this work holds a great promise in the development of carbon-based transparent conductive coatings to replace costly indium tin oxide-based transparent conductive coating, which is necessary for energy saving windows, solar cells, display and LED etc.
