ULTRASONIC CHARACTERIZATION OF POLYMERIC MATERIALS

Pulse in polymer
Dynamic spectrum (G',G") continued in MHz range using ultrasound

  • Properties of Polymers in the MHz Range
  • Relaxation spectra (shear and compression)
  • Development of theories for characterizing the morphology of polymer emulsions
  • Investigation of resonances in multiphase polymeric systems
  • Application of ultrasound to other heterogeneous media
