Journal ArticleDOI
Non-symmetrical dielectric relaxation behaviour arising from a simple empirical decay function
Graham Williams,David C. Watts +1 more
TL;DR: In this article, the empirical dielectric decay function γ(t)= exp −(t/τ 0)β was transformed analytically to give the frequency dependent complex dielectrics constant if β is chosen to be 0.50 in the range log(ωτ0) > −0.5.
Book
Anelastic and Dielectric Effects in Polymeric Solids
TL;DR: Menard et al. as mentioned in this paper discuss the use of dynamic mechanical analysis (DMA) as a tool for thermal analysis, rheology, and materials science in the analytical laboratory.
Journal ArticleDOI
Further considerations of non symmetrical dielectric relaxation behaviour arising from a simple empirical decay function
TL;DR: The empirical dielectric decay function ϕ(t)= exp −(t/τ0)β, 0 0, but significant corrections may have to be applied for β > 0.5 and log ωτ0 < 0.
Journal ArticleDOI
Conference on Electrical Insulation and Dielectric Phenomena
TL;DR: The discovery and development of manmade polymer materials dates from the pioneering works of Goodyear (vulcanized rubber) and Hyatt (celluloid plastics) in the mid-nienteenth century, and to Baekeland (Phenol-formaldehyde resins) at the beginning of this century, the remarkable growth of the synthetic fiber, rubber, and plastics industries followed the preparative achievements of the I.C.I.
Book ChapterDOI
Molecular aspects of multiple dielectric relaxation processes in solid polymers
TL;DR: In this article, the authors present a unified approach to interpret the relaxations of amorphous polymers in a unified way, independent of the details of chemical structure, by use of the time-correlation function approach to partial and total relaxations.
