Graphene based polymer nanocomposites (GPNs) are a class of materials that combine the unique properties of graphene with the versatility of polymers. Graphene is a two-dimensional material made of carbon atoms arranged in a hexagonal lattice. It is an excellent conductor of electricity and heat, and it is also very strong and flexible. Polymers are a class of materials that are made up of long chains of repeating units. They are typically flexible and lightweight, and they can be easily processed into a variety of shapes.

GPNs combine the best properties of both graphene and polymers. They are lightweight, flexible, and easy to process, and they also have excellent electrical and thermal conductivity. This makes them ideal for a variety of applications in electronics, including batteries, solar cells, and sensors.

The properties of GPNs depend on the type of graphene and polymer used, as well as the weight percentage of graphene in the composite. In general, GPNs have the following properties:

Electrical conductivity: GPNs are excellent conductors of electricity. The electrical conductivity of a GPN increases with the weight percentage of graphene in the composite.
Thermal conductivity: GPNs are also excellent conductors of heat. The thermal conductivity of a GPN increases with the weight percentage of graphene in the composite.
Mechanical strength: GPNs are strong and flexible. The mechanical strength of a GPN increases with the weight percentage of graphene in the composite.
Lightweight: GPNs are lightweight materials. The density of a GPN is typically less than 1 g/cm3.
Flexible: GPNs are flexible materials. They can be easily bent or folded without breaking.
Easy to process: GPNs can be easily processed into a variety of shapes. They can be extruded, molded, or printed.

GPNs have a wide range of applications in electronics, including:

Batteries: GPNs can be used to improve the performance of batteries. They can increase the capacity of batteries, and they can also make them more durable.
Solar cells: GPNs can be used to improve the efficiency of solar cells. They can increase the amount of light that is absorbed by solar cells, and they can also reduce the amount of heat that is lost.
Sensors: GPNs can be used to make sensors that are more sensitive and more selective. They can be used to detect a variety of gases, liquids, and solids.
Displays: GPNs can be used to make displays that are brighter, more colorful, and more flexible. They can also be used to make displays that are more energy efficient.

GPNs can be fabricated using a variety of methods, including:

In situ polymerization: In situ polymerization involves polymerizing a monomer in the presence of graphene. This method produces GPNs with a uniform dispersion of graphene in the polymer matrix.
Solution blending: Solution blending involves mixing a solution of graphene in a solvent with a solution of polymer in a solvent. This method produces GPNs with a random dispersion of graphene in the polymer matrix.
Melt blending: Melt blending involves mixing molten graphene with molten polymer. This method produces GPNs with a uniform dispersion of graphene in the polymer matrix.

GPNs are a promising class of materials for a variety of applications in electronics. They combine the unique properties of graphene with the versatility of polymers. This makes them ideal for applications where high electrical and thermal conductivity, mechanical strength, and flexibility are required.

As research on GPNs continues, we can expect to see even more applications for these materials in the future.
