Application areas of graphene

With the gradual deepening of the study of the properties, structure and preparation methods of graphene, the excellent properties of graphene are also widely used in various fields. The more mature fields of graphene application research mainly include graphene composite materials, electronic components, conductive inks and hydrogen storage materials.

1. Graphene composite materials

Because of its loose and porous structure, high conductivity and high material strength, graphene can be combined with other materials of different properties to form composite materials. The Franli plant prepared TiO2/graphene composites by hydrothermal method to overcome the defect that the catalyst nanoTiO2 is easily decomposed under light Through experiments, it was found that TiO2/graphene composites can work normally under visible light, and the efficiency of catalytic degradation of organic matter is significantly higher than that of nanoTiO2.

Graphite phase carbon nitride (g-C3N4) during the catalytic process, the resulting photogenerated electron-hole pair of the composite will inhibit its catalytic efficiency. Based on this shortcoming, g-C3N4/graphene composites were successfully prepared by calcination. Through experiments, it was found that the catalytic efficiency of the composite material on the degradation of rhodamine b (RHB) was increased by 43.2%, indicating that after the addition of graphene, the composite rate of the photogenerated electron-hole pair of graphite phase nitride carbon decreased significantly, and the catalytic efficiency was improved. Based on the shortcomings of bismaleimide such as easy fracture and poor toughness, graphene/bismaleimide composites coated with SiO2 were prepared.

Through experiments, it was found that the mechanical properties of the composite material were further improved on the basis of the original, compared with the raw materials, the impact strength was 23.0kJ/m2, an increase of 150%, and the bending strength reached 157.4Mpa, an increase of 58%.

2. Graphene electronic components

Graphene’s ultra-high electron mobility, specific surface area and mechanical properties indicate that it is a very ideal nanomaterial, especially for microelectronic components such as transistors and integrated circuits. The United States successfully manufactured the first graphene transistor, which can work normally at a frequency of 100GHz; After that, they successfully assembled the first graphene integrated circuit, which can mix at up to 10 GHz and can withstand high temperatures of 125 °C. It fully shows that graphene is a very ideal electrode material.

3. Graphene hydrogen storage material

Hydrogen energy is considered to be an environmentally friendly, efficient and pollution-free new energy source, hydrogen is characterized by light weight, good thermal conductivity, universal presence and high calorific value, especially in today’s increasingly depleted fossil energy, for hydrogen storage research is particularly important. graphene is considered an ideal hydrogen storage material because of its excellent properties, large specific surface area and ultra-high mechanical strength.

4 .Graphene is used in other ways

The application of graphene in medicine is mainly in the form of graphene derivatives, such as biological components, disease diagnosis and drug transportation, and has a very broad application prospect. Franli found through experiments that after the Franli plant improved the graphene, the drug can function normally under normal physiological conditions and will not have any impact on the human body. graphene coatings not only have the cathodic protection of epoxy zinc-rich coatings and the shielding of glass flake coatings, but also have excellent adhesion, waterproofness and toughness. Therefore, the corrosion resistance of graphene coatings is better than that of any existing heavy anti-corrosion coatings, and it is a coating with excellent performance and broad application prospects.

The application of graphene electric heating film brings revolutionary changes to traditional clothing. The heating speed is extremely fast, and it can reach 40 degrees Celsius and above in a few seconds, and the controllable constant temperature under low voltage (5V) continues for 3 to 5 hours. With intelligent temperature control, the wearer can adjust the inner core of the garment to a comfortable temperature.

The Franli factory can provide you with better quality graphene for materials, chemistry, electricity, optics and many other disciplines. Using higher-quality graphene can greatly enhance its use value and use it more perfectly when manufacturing products.
