Doppler broadening spectroscopy of carbon black and carbon black-filled rubbers
Published 2001“…This is due to (1) reduction in positronium formation as carbon black is added to the rubber, and (2) positron trapping at the carbon black–rubber interface, which depends on the carbon black morphology. The S parameter decreases with the carbon black surface area. The S parameter does not depend on the sample mixing time.…”
