Figure 2. The representative models and thermal conductivity (κ) of SCP with different atomic masses of X atoms (m_X) calculated by equilibrium molecular dynamics (EMD) simulations at room temperature.

(a) The thermal conductivity of SPEC (m_X = 1 g/mol) versus chain length (L). (b) The thermal conductivity of Model C-X with varied m_X. (c) The thermal conductivity of Model C-H_mY_n with variable fraction of H atoms Φ_H, where Φ_H is defined as the percentage of H atoms in the total H atoms and Y atoms.
