To improve the dispersion of MWCNT in Epoxt/Vitrimer matrix composites, PMMA-b- PDMAEMA(pyrene) were attached on the surface of MWCNT by noncovalent functionalization. This multiamphiphilic compatibilizer was synthesized by RAFT Polymerization. Then pyrene was introduced by simple reaction. The weight fraction of PMMA and PDMAEMA is 7:3. In the case , pyrene groups can also generate pi-pi stacking with the MWCNT. The noncovalent functionalization of MWCNT was effective in improving the composite's mechanical, electrical properties due to their enhanced dispersion and strong affinity with the epoxy matrix. The incorporation of noncovalently functionalized MWCNT into the Graphene nano platelets yielded enhanced 3-D structure then, mechanical and electrical properties is inhanced
