One example of a novel synthetic material is graphene. Graphene is a two-dimensional sheet of carbon atoms arranged in a hexagonal lattice, forming a single layer of graphite. It is an incredibly thin yet strong material with exceptional electrical and thermal conductivity.

Graphene was first isolated and characterized in 2004 by Andre Geim and Konstantin Novoselov, who received the Nobel Prize in Physics in 2010 for their discovery. They obtained graphene by a process known as mechanical exfoliation. They used adhesive tape to peel layers of graphite, repeatedly splitting it until they obtained individual layers just one atom thick, which turned out to be graphene.

The synthesis of graphene has since been refined and expanded. Chemical vapor deposition (CVD) is one widely used method for growing graphene on metal substrates. In this process, a carbon-containing gas, such as methane, is introduced into a chamber containing a metal catalyst at high temperatures. The carbon atoms in the gas react with the catalyst, leading to the growth of graphene on the substrate.

Graphene has numerous remarkable properties, making it a versatile material with various potential applications. Its exceptional electrical conductivity makes it suitable for use in electronics, such as transistors, flexible displays, and sensors. Its strength and lightness make it promising for composite materials, such as reinforcing agents in polymers or composite structures. Graphene's high thermal conductivity enables its use in heat dissipation applications. Additionally, its impermeability to gases makes it suitable for applications such as membranes for water filtration or gas separation.

Furthermore, graphene's potential extends beyond traditional materials. It has shown promise in energy storage, as a material for supercapacitors and batteries due to its high surface area and electrical properties. It has also been explored for use in biomedical applications, such as drug delivery systems, tissue engineering scaffolds, and biosensors, due to its biocompatibility and unique properties at the nanoscale.

Although graphene is still in the early stages of commercialization, research and development efforts continue to explore its full potential across various industries. As scientists further understand its properties and fabrication techniques improve, graphene holds the promise of revolutionizing numerous fields with its exceptional characteristics and versatility.
