Carbon-based materials are substances primarily made up of carbon atoms. These materials can be found in various forms, such as graphite, diamond, and organic compounds. They play a crucial role in everyday life, from the graphite in pencils to the diamonds used in jewelry. Carbon's unique ability to bond with other elements allows for a wide range of structures and properties, making it essential in many industries. In addition to natural forms, carbon-based materials are also engineered for specific uses. For example, carbon nanotubes are tiny cylindrical structures that have remarkable strength and electrical properties, making them valuable in electronics and materials science. Overall, carbon-based materials are fundamental to both nature and technology.
