Introduction and application
Hexafluoredianhydride (also known as 4, 4' -(hexafluoropropyl) diphthalic anhydride, 6FDA, CAS No. 1107-00-2) is one of the most widely used dihydride monomers, and the most widely used dihydride monomer among the colorless transparent polyimides.The glass transition temperature of polyimides synthesized from hexafluorodic anhydride is usually above 300°C, and their mechanical and electrical properties are well balanced. So far, they are still the most representative polyimides containing fluorine.
At present, the application of fluorine-containing polyimide is mainly used in the field of optics, which is widely used in optical communication, colorless transparent flexible circuit board, solar cell lining, organic flexible transparent conductive film lining, for example, being used for making colorless transparent film on TV or mobile phone folding screen.

簡介及用途
六氟二酐（也即4, 4' -(六氟異亞丙基）二鄰苯二甲酸酐、6FDA，CAS No. 1107-00-2)是應用最廣泛的二酐單體之一，也是目前無色透明聚酰亞胺中使用量最大的二酐單體。由六氟二酐合成的聚酰亞胺的玻璃化溫度通常在300°C以上，機械性能和電性能均衡性良好，到目前為止仍是最具有代表性的含氟聚酰亞胺。
目前含氟聚酰亞胺的應用主要發展到光學領域，在光通信、無色透明柔性線路板、太陽能電池襯底、有機柔性透明導電膜襯底等應用廣泛，例如用于制作電視或者手機折疊屏幕上的無色透明膜。
