two covalently bonded monomers is over 100 times faster than between two non-bonded monomers. Therefore, a delicate balance between these two contributions often provides a guiding tool for the design of tailor made polymeric materials with extraordinary thermal properties. Traditionally most studies have investigated k in the linear polymeric materials, the recent interests have also been directed towards the amorphous and semi-crystalline epoxy networks. Using molecular dynamics simulations, we investigate the factors effecting k of epoxy networks. We emphasize on the importance of the bond types and their influence on the microstructures of amorphous [1] and semi-crystalline [2] networks, with a goal to provide a guiding principle for the tunability in k. While these results are compared with the existing experiments, we also make predictions.
