Carbon-based materials are substances primarily composed of carbon atoms. These materials can be found in various forms, including solids like graphite and diamond, as well as in complex structures like polymers. They play a crucial role in everyday life, being used in everything from construction to electronics. The versatility of carbon allows it to bond with many other elements, leading to a wide range of properties. For example, carbon nanotubes are known for their strength and conductivity, while organic compounds are essential in biological processes. This diversity makes carbon-based materials vital in science and industry.
