Effect of non-covalent functionalized graphites nanoplatelets on the thermal conductivity of epoxy composites |
| 초록 |
The PDMAEMA-b-PMMA ionic block copolymer (PIB) compatibilizers was synthesized by the reversible addition fragmentation chain transfer (RAFT) polymerization. Non-covalent functionalization was used to functionalize graphites nanoplatelets (GNPs) through π–π stacking of pyrene molecules with a functional segmented polymer chain. The biphenyl molecules of ionic block copolymer compatibilizers were used to improve crystallinity of GNPs/epoxy composites. The BP_PIB functionalized GNPs/epoxy composites showed about 7.75% higher degree of crystallinity than epoxy resin. Furthermore, The BP_PIB functionalized GNPs/epoxy composites exhibited in a remarkable improvement in the thermal conductivity. The thermal conductivity of 30 wt.% BP_PIB-GNPs/epoxy has about 23.4% higher than that of pristine GNPs/epoxy composites. The BP_PIB on the GNPs surface not only plays an important role to facilitate a homogeneous dispersion in the polymer matrix but also improves the GNPs–polymer interaction. |
