Molecular dynamics in thin films of isotactic poly(methylmethacrylate) – revisited

Autor: Lutz Hartmann, Anatoli Serghei, Friedrich Kremer

Publikováno v: Journal of Non-Crystalline Solids. 353:4330-4333

The molecular dynamics in thin films of isotactic poly(methylmethacrylate) is investigated by broadband dielectric spectroscopy. No shifts in the mean relaxation time of the dynamic glass transition are detected down to a film thickness of 6.6 nm. Th

Publikováno v: Acta Physica Polonica A. 104:527-536

The complex dielectric permittivity of 4-(2-hexyloxy-ethyloxy) 4'-cyanobiphenyl measured in the frequency range from 0.03 Hz to 10 9 Hz is presented. Monotropic sequence of thermodynamic phases was found with two stable phases (isotropic and crystal)
