Key Properties

High thermal stability (high melting point)
Dual amine + hydroxyl functional groups for crosslinking / reactive modifications
Aromatic backbone ensures mechanical strength and rigidity
Good solubility in polar aprotic solvents (e.g. DMF) for polymerization
Moderate polarity and hydrogen bonding capability enhance adhesion / interface compatibility

Key Applications of BAP

High-Performance Polymers: Serves as a monomer for synthesizing polyimides, polyamides, and polybenzoxazoles (PBOs), used in aerospace composites, engineering plastics, and structural materials requiring heat resistance and durability.

Gas Separation Membranes: Incorporated into thermally rearranged polybenzoxazoles (TR-PBOs) derived from o-hydroxy polyimides, offering high gas permeability and selectivity (e.g., for CO₂/CH₄ separation, H₂ purification), ideal for natural gas processing and biogas treatment.

Electronics and Optoelectronics: Utilized in insulating materials for semiconductors, optical films, OLED/LCD displays, and electronic components, leveraging its low dielectric constant and electrical insulation properties.

Flame-Retardant Materials: Employed in epoxies, polyurethanes, composites, textiles, and coatings for fire safety applications, providing inherent flame resistance without additional retardants.
Energy Applications: Applied in high-temperature fuel cells and related components, benefiting from its stability in harsh environments.
