Title:
POLYMER PRECURSOR, AND POLYMER THIN FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231807
Kind Code:
A1
Abstract:
A polymer precursor comprises a repeat unit derived from an aromatic dianhydride and an aromatic diamine; at least one carbon atom on an aromatic ring in the aromatic dianhydride and/or the aromatic diamine is connected to a fluorine atom by means of a C-F single bond; a polymer thin film is prepared by using a specific process, so that the polymer thin film can have both good thermodynamic properties and good optical properties, meeting application requirements of flexible electronic components in electronic devices.
