Morphological and Computational Analysis of Additively Manufacturable Polyimide Precursors: Implications for Rationally Designing New Polyimide Structures

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
Multiscale experiments and DFT calculations establish how polyimide precursor choice governs additively manufactured morphology. PMDA/ODA and PMDA/DDS printed via a polysalt vat photopolymerization route are compared by SEM, SAXS/WAXS, and TGA. PDMA/DDS displays reduced π‐stacking and lower thermal stability compared to PMDA/ODA.
