Graphene – the strongest material known to science – is used to create everything from condoms to night-vision contact lenses. Now, thanks to the ingenuity of Spain-based The Graphene Company, paint containing the world’s “thinnest, strongest and most conductive” substance is hitting shelves in the UK. The new lime-based paint is incredibly thin, beneficial for the environment and capable of making your home, or any building, more efficient. Because Graphenstone is composed of a lime-base with a hexagonal lattice of carbon atoms one atom thick thanks to the inclusion of graphene, the lime-based paint has superconductivity, which means it can improve the thermal regulation of buildings.
