Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Nanotechnology

Background:

  • Covalent organic frameworks (COFs) show promise for diverse applications.
  • Poor solution processability of COFs currently limits their widespread use.
  • Developing processable COFs is crucial for advancing materials applications.

Purpose of the Study:

  • To engineer covalent organic frameworks (COFs) for improved solution processability.

Main Methods:

  • Pore engineering of hydrazone- and β-ketoenamine-linked COFs using hydrophilic side chains.
  • Fabrication of free-standing COF films (COF-PEO-3 and TFP-PEO-3).
  • Mechanical characterization (Young's modulus) and dielectric property assessment.

Main Results:

  • Successfully improved the processability and solubility of COFs.
  • Produced flexible, crystalline COF films with Young's moduli of 391.7 MPa (COF-PEO-3) and 1034.7 MPa (TFP-PEO-3).
  • Demonstrated high dielectric constant and breakdown strength in TFP-PEO-3 film-based capacitors, achieving 11.22 J cm⁻³ discharged energy density.

Conclusions:

  • A general method for producing solution-processable COFs and flexible films has been established.
  • The engineered COFs exhibit excellent mechanical properties and suitability for dielectric devices.
  • These advancements hold significant potential for flexible electronics and energy storage applications.
