Porosity of Polymers and Positron Annihilation Data

摘要：

Membrane materials and polymer sorbents, polymers with highly developed free volume and specific surface, are of great technical importance. At the same time, positron annihilation lifetime (PAL) studies of these materials and some additional experiments give a chance to learn about size distributions of elementary free volumes (EFV) of these materials. Particularly to answer the question whether the distributions are of Gaussian character, as it is suggested in 1,2 or they have some asymmetry 3,4 or even some multi-component character 4, also to check some ideas on the ways of o-Ps trapping.
