      For polymers, glass transition temperature, T g, is an important technological parameter because it is the temperature at which most polymers freeze into a solidlike glassy state ().Studies over the past 15 years show that the T g of nanometer polymer films can vary substantially with the film thickness, h, when h is decreased below 50 nm (2–8).

      This chapter reviews the recent experiments involving the dynamics of polymer films with thickness comparable to the gyration radius of the polymer, which overwhelmingly show that their glass transition temperature, T g, depends on the film thickness and can sometimes differ significant from that of the bulk. The greatest mystery is the onset.

ebook. In the last decade extensive studies have been performed on polymer thin films to reveal very interesting but unusual properties such as reduction in the glass transition temperature T g with film thickness and negative thermal expansivity for thin films below about 25 nm, and often some contradictory experimental results have been reported.

It Cited by: The glass transition and the α-process above the glass transition temperature, T g, and the aging dynamics below T g were investigated for single and stacked thin polymer films.

The dynamic heterogeneity of polymer thin films in the glassy state was also evaluated in terms of non-Gaussian parameters. Second, the glass transition temperature of polymer thin films was investigated using inelastic neutron scattering with high-energy resolution to clarify the mechanism of its dependence on film thickness.

Finally, neutron reflectivity was used to study the distribution of glass transition temperature in a multilayered thin film consisting of deuterated polymer Cited by: 4. Glass TransitionTemperature and Dynamics ofα-Process inThin Polymer Films K.

Introduction. The glass transition and segmental dynamics of thin polymer films are influenced by the film thickness and the interfacial interaction between the polymer and the substrate by: Measurements of the glass transition are an indirect probe of the dynamics in thin polymer films, and provide a single value to describe the entire temperature-dependent dynamics of the system being measured.

In addition to the measurements of whole chain diffusion discussed above, there have been a number of recent studies, which focused on measuring the dynamics in thin polymer by: We investigate the glass transition behavior in polymer thin films using a model equation-of-state approach, which involves molecular parameters whose values are determined from fits to bulk information only (pressure–volume–temperature and surface tension data).

Following an earlier proof-of-concept application to freestanding polystyrene (PS) films, here we both extend the study to poly Cited by: Spectroscopy (SHS) have been used to investigate the glass transition of thin polymer films from both the thermodynamic and the kinetic point of view.

Mobility Gradient of Polystyrene in Films Supported on Solid Substrates, by Yoshihisa Fujii, Hiroshi Morita, Atsushi Tak Brand: Springer Berlin Heidelberg. In the last two decades very extensive studies have been performed on polymer thin films to reveal very interesting but unusual properties.

One of the most interesting findings is the decrease in glass transition temperature Tg with film thickness in polystyrene (PS) thin film supported on Si substrate. Another interesting finding is apparent negative thermal expansivity in glassy state for Author: Toshiji Kanaya, Rintaro Inoue, Koji Nishida.

When a polymer is modified so that its glass transition temperature, T g, is decreased (increased) from the inherent value, its dynamics is often supposed to be enhanced (suppressed).For polymer films, there is an ongoing debate about whether a change in T g upon changing the film thickness is accompanied by a correlated change in the dynamics of the by: Glass Transition, Dynamics and Heterogeneity of Polymer Thin Films (Advances in Polymer Science Book ) eBook: Kanaya, Toshiji: : Kindle StoreManufacturer: Springer.

Extensive studies on polymer thin films to date have revealed their interesting but unusual properties such as film thickness dependence of glass transition temperature Tg and thermal expansivity.
