The simplest way to describe graphene is that it is a single, thin layer of graphite — the soft, flaky material used in pencil lead. Graphite is an allotrope of the element carbon, meaning it possesses the same atoms but they’re arranged in a different way, giving the material different properties. For example, both diamond and graphite are forms of carbon, yet they have wildly different natures. Diamonds are incredibly strong, while graphite is brittle. Graphene’s atoms are arranged in a hexagonal arrangement.
Interestingly, when graphene is isolated from graphite it takes on some miraculous properties. It is a mere one-atom thick, the first two-dimensional material ever discovered. Despite this, graphene is also one of the strongest materials in the known universe. With a tensile strength of 130 GPa (gigapascals), it is more than 100 times stronger than steel.
Bottom paint is the paint on a ships hull that is below the waterline.
Due to it being submerged, fouling organisms such as shells, weeds, and slime can harm the structural integrity of your boat hull, which can lead to more expensive repairs down the road.
Excessive marine growth on the bottom of a ship can also increase fuel bill because the engine has to work harder to move the boat through the water. Even worse, bio-fouling can make maneuvering more difficult—which can be dangerous.
