Graphene is going to change the world — or so we’ve been told.
Since its discovery a decade ago, scientists and tech gurus have hailed graphene as the wonder material that could replace silicon in electronics, increase the efficiency of batteries, the durability and conductivity of touch screens and pave the way for cheap thermal electric energy, among many other things.
It’s one atom thick, stronger than steel, harder than diamond and one of the most conductive materials on earth.
