Graphene is a two-dimensional crystal composed of carbon atoms with sp2 hybrid orbitals forming a hexagonal two-dimensional carbon nanomaterial in a honeycomb lattice. Graphene has excellent optical, electrical, and mechanical properties and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and medical delivery. It is considered a revolutionary material in the future.
Graphene is currently the thinnest but hardest nanomaterial in the world. It is almost completely transparent and only absorbs 2.3% of light. Its thermal conductivity is as high as 5300 W/m·K, which is higher than carbon nanotubes and diamond, and worse than diamond. It is hard and 100 times stronger than the best steel in the world. Its electron mobility exceeds 15,000 cm2/V·s at room temperature, which is higher than carbon nanotubes or monocrystalline silicon, and its resistivity is only about 10-6 Ω·cm, lower than copper or silver, it is the material with the smallest resistivity in the world. Because its resistivity is extremely low and electrons move extremely fast, it is expected to be used to develop a new generation of electronic components or transistors that are thinner and conduct electricity faster. Since graphene is essentially a transparent and good conductor, it is also suitable for making transparent touch screens, light panels, and even solar cells.
The graphene is actually very widely used in modified plastics nowdays,The nylon nanocomposite material obtained by uniformly dispersing graphene in the nylon 6 system can greatly improve many properties of nylon 6, such as thermal properties, mechanical properties, flame retardancy and barrier properties, thereby improving the performance of nylon nanocomposite materials. Added value is an important development direction of today's nylon materials.
Graphene nylon is a compound composed of graphene and nylon resin.Graphene is a two-dimensional crystal structure composed of carbon atoms. It has high electrical and thermal conductivity and can improve the electrical and thermal conductivity of fibers. Graphene also has high strength properties, which can increase the durability and strength of nylon fibers.
The preparation method of graphene nylon can be achieved by mechanical mixing, sol-gel impregnation and chemical reduction. Among them, sol-gel impregnation is a commonly used preparation method, which can effectively incorporate graphene into the nylon matrix and maintain its physical and chemical properties. This makes graphene nylon have broad application prospects in fields such as electronic devices, sensors and smart textiles. Graphene nylon has good toughness and wear resistance. Nylon fiber itself has good toughness and wear resistance, and the addition of graphene further improves the performance of the composite material. This makes graphene nylon widely used in fields such as automotive parts, aerospace, and sporting goods.
