Positron Studies of Polymeric Surfaces

摘要：

In recent years there has been a lot of interest in the investigation of microstructural properties of polymers using positron annihilation spectroscopy (PAS). One of the great successes in this line of research is the determination of defect properties, such as free volume holes, at an atomic scale (0.2-2 nm) in polymers 1. Application of the PAS to determine the structural properties of the surface including the free volume holes and the glass transition temperature requires a basic understanding of the mechanism of positronium (Ps) formation and annihilation at the polymeric surface 2.
