Article Synopsis
- Thermal transport simulations focused on how the structure of semi-crystalline polyetheretherketone (PEEK) and the addition of boron nitride (BN) sheets affect thermal conductivity.
- Molecular-level analysis helped identify the optimal structure of PEEK, emphasizing the importance of amorphous chain length and linkage conformations like loops, tails, and bridges.
- The addition of BN sheets created longer heat transfer paths, improving the thermal conductivity of PEEK/BN composites, although excessive aggregation of BN sheets disrupted these pathways and limited conductivity improvements.
In this study, the effect of interfacial interaction between solvent and sheets on the exfoliation of sulfur-doped reduced graphene oxide (SrGO) sheets was studied, using molecular dynamics simulations. Four organic solvents of toluene, tetrahydrofuran, N-methyl-2-pyrrolidone, and sulfolane, were used in this simulation. An insertion simulation considering the size effect of insertion molecules was used to determine the insertion efficiency of the solvent molecules.
