Radical-forming polyamides for self-decontamination coatings

Design and synthesis of thermally stable polyamides with improved solubility based on an asymmetrical aromatic diamine containing phenoxy substituted benzophenone segment was the main objective of this work. These polymers were easily soluble at room temperature in polar aprotic solvents and even in less polar solvents, such as tetrahydrofuran. The polymers showed excellent thermal stability, up to 385°C, and exhibited glass transition in the range of 225-256°C. All the polymers emitted an intense blue light upon irradiation with UV light, due to the emission from the benzophenone chromophore. The free-standing films having the thickness in the range of tens of micrometers obtained from these polymers were flexible, tough, and maintained their integrity after repeated bendings. To investigate the radical-forming ability of the polyamides for decomposing surrounding harmful materials, degradation of methylene blue by the polymer films was studied.
