Note: Nano graphen sensor gas nanoparticle sensors have unique optical properties, and the nanotechnology of these nanostructures has led them to use this nanomaterial to develop small tools, such as low-power sensors. Graphene nanomaterials threaten other nanomaterials from a gas sensor point of view.
Gas sensors with (nanomaterials) Stable, sensitive and simple electronic sensors that can detect very small amounts of gases, such sensors can be used to identify harmful substances or hazardous chemical agents, among all nanomaterials, carbon nanomaterials (graphene) They are a great option for this. Carbon nanomaterials, due to their inherent properties, have a high potential for low dimension, and an area for the production of automatic sensors. Carbon structures have a high level that is ideal for sensors. Unlike multi-crystal materials, such as numbers, there are no grain boundaries, which is why Metal oxides, carbon materials that become a long-term wave of sensor stability. Some carbon materials, such as carbon nanotubes and graphene, have high-quality crystal lattice nanotubes, so carriers move at high speeds in these structures while making little noise. Since these two factors play a very important role in creating conductive properties. It is simpler to control and multidimensional and has a high quality crystal structure.
The electromagnetic properties of carbon (graphene) nanotubes make it possible to use these materials in flexible electronic devices such as the Nano graphen sensor . The low energy consumption of carbon nanotube-based devices makes it possible for these devices to operate independently and without the need for an external charger . The movement of electronic signals in a chemical environment has advantages over optical methods . In the construction of sensors, graphene, as one of the new carbon allotropes, is anticipating carbon nanotubes in the construction of sensors . But carbon nanotubes are not limited to graphene and nanotubes.
Conclusion:
One of the main reasons for the sensor's interest in carbon nanotubes (graphene) is that in addition to having a regular nanoscale tubular structure, these materials also have significant stability, so they are very stable even if they are not operating . However, there are a wide range of nanomaterials .
