Dispersion and interaction of graphene oxide in amorphous and semi-crystalline nano-composites: a PALS study

Maurer, Frans LU and Rodriguez Arza, Carlos LU (2015) 11th International Workshop on Positron and Positronium Chemistry (PPC) In 11th International Workshop on Positron and Positronium Chemistry (PPC-11) 618. p.012020-012020
Abstract
The influence of dispersion and interaction of Graphene Oxide (GO) in semi-crystalline Polyhydroxy butyrate (PHB) and glassy amorphous Poly(tBP-oda) is explored by Positron Annihilation Lifetime Spectroscopy (PALS). The ortho-Positronium lifetimes which represent the main free volume hole size of both polymers are mainly affected by the large differences in internal stresses built up by the shrinkage of the polymers during their preparation, restricted by the platelet structure of GO. The ortho-Positronium intensities, which represent the ortho-Positronium formation probabilities, suggest a strong dependency of on the dispersion of the nano-particles and their aspect ratio.
