A study systematically investigated thickness dependence of glass transition temperature (Tg) and thermal expansion (CTE) at glassy and rubbery states for the PS films that were supported on chemically identical polystyrene (PS)-grafted substrates using in situ ellipsometry. A grafting-to method with hydroxyl end-functionalized polystyrenes (PSOHs) was used to generate PS-grafted substrates. Temperature-dependent film thicknesses of PS films were evaluated to obtain Tg and CTEs.
