## Figure 1.
The thickness-dependent elastic modulus of PS thin films at . The symbols circle and square are the experiment results for molar weight T = 295 KM_{w }= 1800 and 114 kg/mol, respectively [12]. The solid curve is plotted with the calculation results obtained from Equation 3,
where the parameters that determine the T_{g}(h) in Equation 4 are c = 1/2, h_{0 }= 5 nm, ΔC_{pb }= 30.7 J mol^{-1 }K^{-1 }= 1.919 J g atom^{-1 }K^{-1}, and T_{gb }= 375 K [4].
