One of the biggest ADVANTAGES of graphene is its high electrical conductivity. This conductivity is mostly dependent on the quality of graphene we use.
Graphene coatings and composites can bring electrical conductivity to materials that are normally isolators. This opens a whole new area of possibilities for utilizing graphene in electronics, wearables and the Internet of Things. Although, electronics require a premium quality graphene.
As you already know, graphite is not electrically conductive and more than 10 layers of graphene behaves like graphite. To achieve electrical conductivity you need a maximum of 10 layers.
The features of graphene composites are influenced by the amount of graphene and its dispersion. For instance, graphene can enhance electrical conductivity of epoxy for about 100,000 times.
Graphene's diamond-hardness means it can be utilized in electronic components. It's actually thinner and tougher than the materials used these days.
We can go even further and instead of having devices whose shape incorporates a screen, we can make the entire surface a screen.
It is widely believed that graphene will have commercial use in opto-electronics such as LCD's, OLEDs and touch screens among others. Graphene is almost transparent hence it's perfect for screens, tablets or smartphones. But once again, to achieve all this you need the best quality graphene.
Lighter, faster charging and more powerful batteries are among the main goals of many companies, even military. In the future, we can even replace lithium with graphene .
As graphene allows us to make devices slight enough without sacrificing power or stamina the wearable designers are already creating concepts and prototypes for graphene enhanced textiles.
This is a real example of using graphene in fashion industry. CuteCircuit's dress has graphene enhanced sensors; deep breaths turn the lights from purple to turquioise, while lighter ones make them go from orange to green.
Most of what you've read on the internet about graphene is about its future potential. However, this is rapidly changing. We could already see automotive companies experimenting with graphene batteries and the first prototypes of electrically conductive clothes or electronics.
