With the continuous development of society, the application of high-performance plastics is more and more extensive, and polycarbonate (PC), as one of the best, has attracted much attention. Polycarbonate is a linear polymer compound with excellent physical and chemical properties, so it has been applied in many fields such as industry, medical treatment, electronics, household appliances, automobile and aerospace.

polycarbonate was first developed by Baekeland Chemical Company in 1953 and was mainly used in diving lenses and other applications in the early days. In the 1960 s and 1970 s, polycarbonate has been widely developed and applied, widely used in bowls, cans, dishes, bottles, caps and other daily necessities, with the advancement of new technologies, the scope of application of polycarbonate continues to expand, Is gradually replacing the status of some traditional materials.

1. the characteristics of polycarbonate

1. high hardness: relative to the general plastic, polycarbonate material has a high hardness, which is due to the stability of the molecular structure of polycarbonate material, which is also polycarbonate material in the eyepiece aircraft, construction and other fields have been widely used one of the reasons.

2. Impact resistance: Compared with other ordinary plastics, polycarbonate material has better impact resistance and other properties, can be used at 0 ℃ ~-40 ℃, not easy to deformation and fracture, and high temperature resistance.

3. High temperature resistance: Polycarbonate has good high temperature resistance, and its glass transfer temperature can reach above 140 ℃. It is suitable for battery cases, CD trays, lamp shades and other products of electronic products.

4. Chemical resistance: Polycarbonate material is not easy to be corroded by acid and alkali, and it is not easy to be affected by moisture, which makes it widely used in metal surface coating, and it is also widely used in the manufacture of liquid crystal displays and electric Vehicle batteries and so on.

5. Biocompatibility: Polycarbonate material has good biocompatibility, so it will not cause harm to the human body and is suitable for manufacturing medical devices.

2. Polycarbonate Applications

1. Electronics: PC materials are widely used in electronic products, such as computer casings, keyboards, electronic toys, TV casings, cameras and other products.

2. Automotive: Polycarbonate materials are also widely used in automotive parts, such as rearview mirror housings, lamp covers, automotive interiors, windshields and other products.

3. Medical: PC materials have good biocompatibility and are widely used in the manufacture of medical devices and equipment. Such as compressed sand sacs, syringes, surgical supplies, etc.

4. Aerospace: Polycarbonate material has excellent performance and is widely used in aircraft, spacecraft and other fields, such as aircraft portholes, spacecraft shells and other products. The future development trend of

3. polycarbonate

At present, polycarbonate is one of the important varieties of high-performance plastics, and there are unlimited market prospects in the future. With the arrival of new development trends such as artificial intelligence, automotive electrification, and new energy, polycarbonate will also have a wider range of applications, and the technological research and development and manufacturing process of polycarbonate materials will continue to be optimized and improved. Its future development brings more potential and opportunities.

With the continuous development of science and technology, polycarbonate materials will also be applied in more fields and continue to be favored by the global market. In this paper, the characteristics, application fields and future development trends of polycarbonate materials are interpreted. It is believed that this high-performance plastic will lead the development of more fields in the future.
