Discretized Wiener-Khinchin theorem for Fourier-Laplace transformation: application to molecular simulations
Akira Koyama, David A. Nicholson, Marat Andreev +3
The Wiener-Khinchin theorem for the Fourier-Laplace transformation (WKT-FLT) provides a robust method to calculate numerically single-side Fourier transforms of arbitrary autocorre…
Dielectric relaxation of thin films of polyamide random copolymers
Natsumi Taniguchi, Koji Fukao, Paul Sotta +1
We investigate the relaxation behavior of thin films of a polyamide random copolymer, PA66/6I, with various film thicknesses using dielectric relaxation spectroscopy. Two dielectri…
Glassy dynamics in thin films of polystyrene
Koji Fukao, Hiroki Koizumi
Glassy dynamics was investigated for thin films of atactic polystyrene by complex electric capacitance measurements using dielectric relaxation spectroscopy. During the isothermal…
Crossover of aging dynamics in polymer glass: from cumulative aging to non-cumulative aging
Koji Fukao, Sinpei Yamawaki
The aging behavior of polymer glass, poly(methyl methacrylate), has been investigated through the measurement of ac dielectric susceptibility ata fixed frequency after a temperatur…
Glass transition and alpha-relaxation dynamics of thin films of labeled polystyrene
Rodney D. Priestley, Linda J. Broadbelt, John M. Torkelson +1
The glass transition temperature and relaxation dynamics of the segmental motions of thin films of polystyrene labeled with a dye, 4-[N-ethyl-N-(hydroxyethyl)]amino-4-nitraozobenze…
Aging phenomena in polystyrene thin films
Koji Fukao, Hiroki Koizumi
The aging behavior is investigated for thin films of atactic polystyrene through measurements of complex electric capacitance. During isothermal aging process the real part of the…
