How Much Do You Know About Graphene Powder?
Overview: Graphene powder consists of multiple layers of graphene at a microscopic level. When stacked, it appears more layered, opaque, and resembles black powder. Its unique physical properties, such as its ability to generate heat, make it highly sought after. The term “graphene powder” refers to a mixture of single-layer and multi-layer graphene. Its applications are very broad.
Graphene powder is made up of numerous layers of graphene at the microscopic level. When stacked together, it has a layered look and appears opaque, similar to black powder. Its unique physical properties, such as those used in heating products, make it very popular and in high demand. Graphene powder is essentially a blend of single-layer and multi-layer graphene. It has a wide range of applications.
Graphene powder can be categorized into graphene powder and graphene films. Common production methods for graphite powder include mechanical exfoliation, reduction-oxidation, and SiC epitaxial growth. Graphene film production uses the chemical vapor deposition (CVD) method. Mechanical exfoliation involves friction and relative movement between a material and graphene to obtain thin-layer materials. This method is simple and usually retains the complete crystal structure of graphene.
Heating is a building environment control technology developed by humans early on. As heating demand grows, heating equipment and systems have been continuously optimized in terms of human comfort, hygiene, energy equipment size and aesthetics, system and equipment automation, and energy efficiency.
In some areas where gas supply is insufficient but electricity is abundant, it’s not necessary to use gas for heating. People can cook with gas and heat with electricity. This is one of the various explorations in heating methods. During the promotion of clean heating projects, energy supply is a major issue.
Currently, due to the shortage of clean energy such as natural gas in China, the dependency on foreign natural gas increased to 38% in 2017, reaching 43.3% in the first half of 2018. Some local governments find “coal-to-gas” conversion simple and straightforward. Abandoning other feasible clean energy heating methods and hastily adopting “coal-to-gas” conversion not only loses the value of pilot projects but also creates artificial gas supply shortages, exacerbating supply-demand conflicts.
With the development of heating technology and equipment and the diversification of heating methods, the issues arising from the energy structure of coal, gas, oil, and electricity for heating have become increasingly apparent. Natural gas is a highly potential high-quality energy source. Raising the heating temperature by just a few degrees is a waste of resources and it is a non-renewable energy source. The gas supply is small and unstable.
Graphene heaters automatically turn off when the temperature reaches a suitable level. They generate heat when the room temperature is low. These small devices can warm an entire living room, making them a favorite among parents. Graphene products have also gained widespread recognition.
