It is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. It is the fundamental element of other allotropes like graphite, charcoal, carbon nanotubes, and fullerenes. It is the strongest and thinnest material known to exist. Properties of Graphene: Electronic: It has good electrical conductivity. The unique atomic arrangement of the carbon atoms in graphene allows its electrons to easily travel at extremely high velocity without the significant chance of scattering, saving precious energy typically lost in other conductors. Mechanical: Graphene has good strength as it is harder than diamond. Graphene is about 300 times harder than steel. The tensile strength of graphene exceeds up to 1 TPa (Tetra pascal). Graphenes have high electrical conductivity and high optical transparency which makes it for transparent conducting electrodes. For example, a single layer of graphene only absorbs 2.3% of light, so 97.7% of light passes through a single layer, with around 0.1% reflected from its initial trajectory. Chemical: It is chemically most reactive form of carbon. Uses of Graphene: Graphene derivatives are rapidly emerging as an extremely promising class of antimicrobial materials due to their diverse bactericidal mechanisms and relatively low cytotoxicity towards mammalian cells. Graphene has very high carrier mobility but low noise. This property of graphene allows it to be used as the channel in a field-effect transistor. Graphene oxide-made filters could outperform other techniques of desalination. Graphene oxide made membranes also allow water vapour to pass through it, but are impermeable to other liquids and gases. Graphene could be used to produce supercapacitors that have a greater energy storage density than is currently available. Graphene material will also be used in photoelectrochemical energy conversion in sensitized solar cells 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Cancel the best answer Leave an answerCancel replyYou must login or register to add a new answer.
