Multi-dynamic bond reinforced polyurethane elastomer with outstanding damping characteristics and mechanical properties

SLShaolong LiFQFeng QiCDChunyang Di

Key Points

  • The aim is to synthesize a novel chain extender to enhance the properties of polyurethane elastomer.
  • Synthesized a novel chain extender (HDF) with disulfide and imine bonds.
  • Incorporated HDF into polyurethane elastomer (PUE) to assess its effects.
  • Analyzed the mechanical and damping characteristics of the cured PUE.
  • PUE cured with HDF displayed outstanding damping characteristics.
  • Mechanical properties of the modified PUE were significantly improved.

Abstract

We synthesized a novel chain extender (HDF) featuring disulfide and imine bonds and incorporated it into PUE. The PUE cured with HDF exhibits outstanding damping and mechanical properties.
