Key Applications of HFBAPP

High-Performance Polymers: Used as a monomer for synthesizing polyimides and polyetherimides with excellent thermal and mechanical properties, applied in aerospace composites, aviation materials, and high-temperature environments.

Gas Separation Membranes: Incorporated into permeable polyimide membranes for CO₂ capture from the atmosphere and gas transport/separation, leveraging its fluorination for enhanced selectivity and permeability.

Electronics and Optoelectronics: Serves as a building block for low-dielectric polyimides in telecommunication devices, flexible substrates for solar cells (achieving power conversion efficiencies up to 16.1%), and capacitors; also used in microelectronics, liquid crystal displays, and laser materials.

Energy Storage and Advanced Materials: Utilized in polyetherimides for capacitive energy storage (discharge density of 3.6 J/cm³, efficiency 96.5%); also applied in covalent organic frameworks (COFs), specialty coatings, and nanotechnology.
