Movement Of Molecular Chains Of Nylon 1010, The Localized State Distribution And Structure Of The Relationship

The localized state in semi-crystalline polymer is origin from defects, such as structure imperfection, inter-phase, impurities, carbonyl, peroxy free radical, etc. The polymer's complication chain structure and condensed state structure may both lead to various localized state distributions. The corresponding work is an important topic in the field of polymer electronic properties. It helps leading charge storage and transportation properties further in polymer and then has a great meaning on polymer's application in electrics, optics, acoustics, etc. Because of their abstract microcosmic properties, the localized state properties are hardly to be analyzed by common detecting technique.Nylon 1010 is an engineering plastic in common use. Moreover nylon 1010 is a typical semi-crystalline polymer with different microstructure under various thermal histories and thermo-mechanical treatment. The high values of dielectric permittivity at high temperatures are due to charge carrier movement. The investigation of the relationship between localized state and aggregating structure is important both from the fundamental and technological point of view. The work was composed in parts as follows.To deeply understand the molecule movement and localized state properties of nylons prepared under various thermal histories and γ-irradiation, this article chooses nylon 1010 as a model and nylon 6 as a comparison to investigate the relationship between localized state and aggregating structure using TSDC technique combining dielectric relaxation spectroscopy (DRS) technique.1. Polymer chain movement and charge carrier transport in Nylon 1010 were studied by dielectric relaxation spectroscopy. The high values of dielectric permittivity at low frequencies and high temperatures are due to charge carrier movement. There are three relaxation processes above room temperature for nylon...
