Wood could be carbonized with high temperature into wood charcoal. Wood charcoal has high electric conductivity, so it can be used as a functional conductive unit to produce various new types of function materials, such as electromagnetic shielding materials, antistatic materials, and electricthermal materials. The mechanism of wood carbonization was summarized, and the basic properties of wood charcoal and the influencing factors were analyzed. The research progress on functional conductive charcoal at home and abroad was reviewed, and the research focus in the future was put forward. The study was aimed to provide scientific basis for the development and utilization of new types of functional materials.
