Key Applications of TPE-R

High-Performance Polymers: Serves as a diamine monomer for synthesizing semicrystalline polyimides (e.g., with BPDA or PMDA) and copolymers, offering melt-processability and high-temperature resistance for aerospace composites, structural adhesives, and engineering plastics in military and industrial sectors.

Electronics and Electrical Insulation: Utilized in polyimide films, resins, and composites for microelectronics, 5G devices, smartphones, and electromagnetic shielding (e.g., with titanate nanotubes), providing low dielectric constants and high thermal resistance.

Fuel Cell Membranes: Copolymerized with monomers like PEG to produce membranes with high proton conductivity (up to 210 mS/cm) and thermal stability (up to 140°C), suitable for polymer electrolyte fuel cells.

Sensors and Coordination Compounds: Acts as a ligand in metal-organic complexes (0D, 1D, 2D) for sensing nitroaromatic compounds; also used in siloxane-organic networks for advanced materials.

Other Industrial Uses: Employed as a curing/crosslinking agent in epoxy resins, powder coating matting agents, PVC plasticizers, and in supramolecular chemistry for thiourea derivatives and hydrogen-bonded assemblies; potential in pharmaceuticals and dyes.
