文摘
- •
Effective thermal conductivity (TC) depends significantly on thermal contact resistance (TCR), it decreases sharply for larger volume fraction and TC of core-shell.
- •
Effective TC from present simulation matches well with that obtained by Felske model only if the TCR is negligible.
- •
Maximum effective TC exists when core volume fraction is 0.516 times greater than that of shell regardless of the presence of TCR.
- •
Many good guidance are provided for enhancing the TC of core–shell nanoparticle polymer composites under the effects of TCR.
