East has developed high rigid, high heat resistance, colorless and transparent aromatic polyamide film

Dongli Co., Ltd. (hereinafter referred to as "Dong Li") has announced that it has been developed with a transparent aromatic polyamide film (PI) having an equivalent hardness of the glass and can withstand 1 mm curved radius. In recent years, foldable and bending displays are constantly evolving. It is necessary to replace the traditional glass cover of the display of the display, which requires high hardness and bendable diaphragm. Aromatic polyamides are superior engineering plastics with excellent hardness and heat resistance, and the nature is the only business in the world. Based on this technology, the company has developed high rigid, high thermal resistance, colorless and transparent aromatic polyamide films. Dongli can perform surface processing of the transparent film by using expertise, achieving an ultra-high hardness of 9h and a curved bending of 1 mm is more than 1 mm is more than 1 mm. This product is used on the display surface cover of the display. While obtaining the same scratch with the glass, a thinner and more designed flexible display can be expected. The east has passed unique polymer design techniques, which makes the film have both rigid and heat resistance. While developing a colorless and transparent aromatic polyamide polymer, the characteristics of the aromatic polyamide are successfully generated by deepening the solution of the solution film, and the highest Young's modulus value of 10 GPa is achieved and 5PPM / K. The following thermal expansion coefficients are high rigidity and high heat resistance. At the same time, the company developed a special coating coating of an aromatic polyamide film, which is an organic inorganic mixing layer composed of a high hardness nanoparticle and a polymer dispersant. By fine filling, homogeneous arrangement of nanoparticles by finely filled in an an aromatic polyamide film in high garanti, so that the film is super high, and the film is controlled by controlling the affinity between the aromatic polyamide film and the dispersant. Take care of bending. The film can be applied to a wide range of fields such as flexible display devices, transparent circuit boards, and transparent solar cells. Currently, it has passed the trial in technology, and the possibility of mass production will be further discussed in the future, but it is expected that the final application still needs several years.
