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.

简介及用途
六氟二酐（也即4, 4' -(六氟异亚丙基）二邻苯二甲酸酐、6FDA，CAS No. 1107-00-2)是应用最广泛的二酐单体之一，也是目前无色透明聚酰亚胺中使用量最大的二酐单体。由六氟二酐合成的聚酰亚胺的玻璃化温度通常在300°C以上，机械性能和电性能均衡性良好，到目前为止仍是最具有代表性的含氟聚酰亚胺。
目前含氟聚酰亚胺的应用主要发展到光学领域，在光通信、无色透明柔性线路板、太阳能电池衬底、有机柔性透明导电膜衬底等应用广泛，例如用于制作电视或者手机折叠屏幕上的无色透明膜。
