MIT researchers believe that coal has a special molecular structure that can be used as a basic material for the manufacture of solar panels, batteries, or electronic devices. Coal should be looked at from an angle instead of being burned as fuel. In order to demonstrate that this kind of material traditionally regarded as low-tech has broad prospects for high-tech applications, Jeffrey Grossman, a researcher in the Department of Materials Science and Engineering at the school, successfully developed an electric heating system using coal. Device. This device can be used for defrosting automotive glass and aircraft wings, or as part of biomedical implants. There are many kinds of natural coal, and their electrical conductivity is at most 10 million times different. This means that if there are enough types of coal, researchers can use their electronic properties to create unique electronic components. However, one of the challenges of this work is how to process coal. After exploration, the researchers devised a method: first develop the coal into a powder, then dissolve it in a solution, and finally deposit it on the substrate and form a thin film. Using this method, they thoroughly tested coal films and used them to make electronic components. The researchers found that by adjusting the temperature at which the coal is processed, the optical and electronic properties of the coal film can be changed to achieve the desired effect. In the research report published in the "Nano Express" journal, they also detailed for the first time the chemical, electronic, and optical properties of four different types of coal (anthracite coal, brown coal, and two kinds of coal smoke) films. Researchers said that the application of coal from the perspective of its natural chemical properties has broad prospects. One is that they are rich in natural resources and relatively cheap; the other is simple processing and low cost. In contrast, silicon, which is an important material for electronic chips, is abundant in nature, but it needs to be purified to more than 99.99% for use in electronic products. Ren Shenqiang, an associate professor of mechanical engineering at Temple University in the United States, commented that the new research helps deepen people's understanding of the potential of natural coal applications. It means significant progress in the development of carbon nanomaterials directly from natural coal.
