Mesogen-containing polymer compatibilizer-functionalized graphite nanoplates: size, multi-layer, and dispersion effects on enhanced thermal conductivity of epoxy composites |
| 초록 |
The poly(2-(dimethylamino)ethyl methacrylate)-b-poly(methyl methacrylate) (PDMAEMA-b-PMMA) ionic block copolymer (BPPIB) compatibilizers were synthesized by the reversible addition fragmentation chain transfer (RAFT) polymerization. Non-covalent functionalization was used to functionalize graphites nanoplates (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 BPIB functionalized GNPs/epoxy composites showed about 7.75% higher degree of crystallinity than epoxy resin. Furthermore, the thermal conductivity of 30 wt% BPIB-MGNPs/epoxy has about 23.4% higher than that of pristine GNPs/epoxy composites. The BPIB 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. |
