To address the issues with molecular representation of copolymerized polyimides (PIs) and mini dataset PI powders. We constructed an interpretable machine learning (ML) model for films using weighted-additive Morgan Fingerprints Frequency descriptors developed transfer enhance Thermal Stability (Temperature at 5% weight loss) powders, it is recommended to add conjugated functional groups diamines, control phenyl ring side chains, reduce pyridine hydroxyl groups; select copolyimides (co-PIs); ensure that anhydride directly connected benzene in dianhydrides, avoiding aliphatic cycles. It noteworthy close alignment between experimental results predictions serves confirm a reliable prediction tool. hoped this polymer informatics approach will provide further implementation practical applications other materials.
