Title:
AROMATIC POLYOXADIAZOLE, AND AROMATIC POLYOXADIAZOLE FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/237827
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polymer materials, and in particular to an aromatic polyoxadiazole, and an aromatic polyoxadiazole film and a preparation method therefor. The aromatic polyoxadiazole comprises a repeating unit A and a repeating unit B; the structure of the repeating unit A is shown in formula I; the structure of the repeating unit B is at least one of formula II, formula III, and formula IV. The aromatic polyoxadiazole film obtained according to the technical solution provided by the present invention has high light transmittance. In the wavelength range of 400-800 nm, the light transmittance exceeds 85%, and the maximum light transmittance reaches 94%.
