Abstract.

We present an investigation of the effect of the interaction between a thin polystyrene film and its supporting substrate on its glass transition temperature (\( T_{\rm g}\)). We modulate this interaction by depositing the film on end-tethered polystyrene grafted layers of controlled molecular parameters. By comparing \(T_{\rm g}\) measurements versus film thickness for films deposited on different grafted layers and films deposited directly on a silicon substrate, we can conclude that there is no important effect of the film-subtrate interaction. Our interpretation of these results is that local orientation and dynamic effects substantial enough to influence \(T_{\rm g}\) cannot readily be obtained by grafting prepolymerized chains to a surface, due to intrinsic limitation of the surface grafting density.
