Figure 3.

(A–D) Thermal conductivity of PE-wax films as a function of draw ratios. A: pure PE and PE with 1 wt % waxes. B–D: PE with 1, 2, and 5 wt % waxes. In Figure 3B, the dashed lines are the fitting curves using eq 1 and the value of thermal conductivity with a draw ratio of 1 is set as 0.5 W m^–1 K^–1.^2,5,7
