On the stereochemical nanostructure-based mechanisms of electrical behavior of polymer insulators

The aim of this paper is to highlight the determining factor of some normal stereochemical nanostructures, especially the mmmr and mmmmrx, termini of isotactic sequence, on the ability of PVC, hydrogenated PVC (as a precursor of PE) and PP to accumulate, release and transport space charges. The correlations found for these polymers by using TSM, TSDC and IDC methods, provide an original interpretation of the space charge behavior of these insulators and open new prospects in the field of property/nanostructures relationships and performances.
