A molecular dynamics simulation of polymer crystallization from oriented amorphous state
Akira Koyama, Takashi Yamamoto, Koji Fukao +1
Molecular process of crystallization from an oriented amorphous state was reproduced by molecular dynamics simulation for a realistic polyethylene model. Initial oriented amorphous…
Crystal Growth of Isotactic Polystyrene in Ultrathin Films : Film Thickness Dependence
Ken Taguchi, Hideki Miyaji, Kunihide Izumi +3
The film thickness dependence of crystal growth is investigated for isotactic polystyrene (it-PS) in thin films, the thickness of which is from 20nm down to 4nm. The single crystal…
History Memorized and Recalled upon Glass Transition
Y. Miyamoto, K. Fukao, H. Yamao +1
The memory effect upon glassification is studied in the glass to rubber transition of vulcanized rubber with the strain as a controlling parameter. A phenomenological model is prop…
Dynamics of alpha- and beta- processes in thin polymer films: poly(vinyl acetate) and poly(methyl methacrylate)
Koji Fukao, Shinobu Uno, Yoshihisa Miyamoto +2
Dynamics of thin films of poly(vinyl acetate) (PVAc) and poly(methyl methacrylate) (PMMA) have been investigated by dielectric relaxation spectroscopy in the frequency range from 0…
Growth Shape of Isotactic Polystyrene Crystals in Thin Films
Ken Taguch, Hideki Miyaji, Kunihide Izumi +3
The crystal growth of isotactic polystyrene (it-PS) is investigated in very thin, 11 nm thick films. The it-PS crystals grown in the thin films show quite different morphology from…
Dielectric and Dilatometric Studies of Glass Transitions in Thin Polymer Films
Koji Fukao, Yoshihisa Miyamoto
Dielectric relaxation and thermal expansion spectroscopy were made for thin polystyrene films in order to measure the temperature corresponding to the peak in the loss compon…
