Article Synopsis
- Novel copolyimides were created using specific materials (ODPA, BIS P, and DAP) through a two-step process involving thermal imidization followed by quaternization with methyl iodide.
- The resulting copolyimides were analyzed for structure using various methods (FTIR, NMR, EDX) and showed varying thermal stability and solubility characteristics, especially those with less than 0.3 DAP content.
- The best ionic conductivity (0.234 S cm) was observed in samples with 0.3 DAP and a specific level of quaternization, while higher DAP contents led to instability likely due to hydrolysis.*
The aim of this work is to apply organic-inorganic hybrid salts made of imidazo[1,5-]pyridinium-based cations and halometallate anions as fluorescent agents to modify cross-linked polyurethane (CPU) for the creation of flexible photoluminescent films. The use of ionic compounds ensures excellent dispersion of the luminescent components in the polymer matrix and prevents solid-state quenching. The absence of phase segregation makes it possible to fabricate uniformly luminescent films with a large area.
