Polyethylene oxide (PEO)complexed with molecular iodine ( I 2 ) forming PEO/ I 2 complex composites stand‐free films were investigated using dielectric relaxation, X-ray photoelectron spectroscopy (XPS), UV–Vis spectrophotometry, structural and morphological techniques. Scanning electron microscopy was...
Observation of a fast dielectric relaxation in semi-crystalline poly(ethylene oxide) Our broadband dielectric study has revealed for the first time a relaxation (termed γ′) between the low temperature β and γ-processes of semi-crystalli... J Xing,S Zhang,J Runt - 《Polymer》 被引量: 80...
Analysis of the α, β, and γ relaxations in polychlorotrifluoroethylene and polyethylene: Dielectric and mechanical properties Theoretical models for the ac and e relaxation effects found in chain-folded polymer crystals (single crystal mats and bulk) are presented and compared wit... JD Hoffman,...

For example the technique of thermally stimulated currents170, 171 which is used extensively to detect relaxation processes in solid polymers has not been described. Also polymer electrolytes composed of mixtures of poly(ethylene oxide) or poly(propylene oxide) and metal salts, which are of interest...

This study investigates the development of novel nanocomposite films based on a blend of polyethylene oxide (PEO) and polyvinyl alcohol (PVA) loaded with varying weight percentages of copper cobaltite nanoparticles (CuCo2O4 NPs). The primary objective wa
nBA, the only monomer, only has a medium polar dipole-ester group, and additionally, the ester group connects a butyl at the other end, which serves as lubricants to accelerate polymeric segmental relaxation. On the other hand, the flexible long aliphatic polyether backbone inside CN9021NS can...
and a relaxation spectrum much broader than Debye-type (Bokov and Ye, 2012; Chenet al., 2019; Cross, 1994; Jayakrishnanet al., 2019b; Zhanget al., 2017). Relaxor ferroelectrics generally have value of dielectric constant (>10,000) higher than normal ferroelectrics, and the dielectric const...
Dynamic relaxation phenomena of the double layer upon contact (aging effects) due to ion migration along the surface or from one surface to another and eventually due to ion transfer into the bulk; these processes are again expected to appear for polymeric colloids with a random coil structure....
