Key applications of TFDB
High-Performance Polymers and Polyimides: Used as a monomer for synthesizing colorless, transparent polyimides with low coefficients of thermal expansion (CTE, e.g., 4.2 ppm/K) and high thermal stability (Td5% >500°C), ideal for aerospace composites, flexible electronics, and high-temperature adhesives.
Optoelectronics and Displays: Incorporated into transparent polyimide films for flexible OLED displays, optical waveguides, and photonics, leveraging its UV resistance and low light absorption due to reduced π-π interactions.
Gas Separation Membranes: Utilized in polyimides (e.g., 6FDA-TFMB) for membranes with high gas permeability (e.g., CO₂/CH₄ selectivity up to 188.43) and microporosity, suitable for industrial gas purification and CO₂ capture.
Electronics and Microelectronics: Employed in low-dielectric-constant materials for insulating layers in microchips, printed circuit boards, and flexible electronics, enhancing signal transmission and thermal stability.
Advanced Materials: Applied in covalent organic frameworks (COFs), metal-organic frameworks (MOFs) for catalysis and gas storage, and specialty coatings for aerospace and industrial applications requiring durability and chemical resistance.
