From: Temperature- and thickness-dependent elastic moduli of polymer thin films

Figure 1

The thickness-dependent elastic modulus of PS thin films at T = 295 K. The symbols circle and square are the experiment results for molar weight M 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].
