Fig. 3. Room temperature thermal conductivity of LAPE as a function of the average chain length (L₀) with fixed σ = 1 nm. κ₀ (empty triangle), κ₁ (solid circle), and κ₂(solid square) are computed by eqn (1), while κ_eff (solid triangle) is computed by eqn (4). The dashed lines are drawn to guide the eye.
