Positron annihilation lifetime spectroscopy (PALS) as a sensitive nanoprobe to study the nanoscale microstructure has been widely used.
Topics of the 17 papers include glassy and rubbery polymers, highly permeable polymers, glassy polymers, substituted polyacetylenes, perfluoropolymers, polyimides, zeolite membranes, carbon membranes, polymer membranes for organic liquids, solid-state facilitated transport membranes for the separation of olefins/paraffins and oxygen/nitrogen, using a unified approach to membrane permeation using a solution-diffusion model, and using such methods as positron annihilation lifetime spectroscopy for free volume evaluation in polymers.
10 Morphology of Free-Volume Holes in Amorphous Polymers by Means of Positron Annihilation Lifetime Spectroscopy (Giovanni Consolati and Fiorenza Quasso).
SUMMARY A review of the theory and experience of Positron Annihilation Lifetime Spectroscopy in polymers provided strong evidence that the longest lived annihilation mode occurs in the free volume sites located in amorphous polymers and the amorphous regions of semicrystalline polymers.
Previous studies of uncompatibilized linear low-density polyethylene (LLDPE)/isotactic polypropylene (PP) binary blends have been reported by the authors using techniques such as positron annihilation lifetime spectroscopy (PALS), small angle X-ray scattering (SAXS), density measurements, differential scanning calorimetry (DSC), tensile testing, and Charpy impact testing (1-3).
