Overview

This research demonstrates improved mechanical performance and EMI shielding in carbon fiber composites, suggesting a new composite design approach.

Key Points

  • The study aims to enhance both mechanical properties and electromagnetic interference shielding capability of carbon fiber composites.
  • Developed a multiscale interfacial modification strategy for carbon fibers.
  • Grew a Zn-based metal-organic framework on carbon fiber using a polydopamine interlayer.
  • Applied a two-step calcination process to create a ZnO/C hybrid coating.
  • Deposited a conductive PEDOT:PSS layer to build a hierarchical conductive network.
  • Increased interlaminar shear strength by 44%.
  • Elevated flexural strength by 41%.
  • Enhanced flexural modulus by 87%.
  • Achieved electromagnetic shielding effectiveness of 44 dB.
