What is it about?
This work studies the correlations between the molecular structure, thermal conductivity and other physical properties of polymer. By molecular engineering, liquid crystalline long-range order is found to be important for the heat transport in polymer.

Why is it important?
Molecular engineering is important to design the molecular structure of polymers to meet their various applications in industry and study the correlations between the molecular structure and other physical properties. By controlling precise ethylene linker length in the molecular structure of epoxy resin, we find a giant odd-even effect of ethylene linker length on liquid crystal formation, mass density, longitudinal elastic constant, and thermal conductivity. The thermal conductivity of liquid crystalline epoxy resin in this work reaches 1.0 W/(m K), which is 5 times of common polymer.
