The influence of polymer modifier chain length on the thermal conductivity of polyamide 6/graphene (GA) nanocomposites, including through-plane (lambda(z)) and in-plane (lambda(x)) directions were investigated. Here, three chain lengths of double amino-terminated polyethylene glycol (NH2-PEG-NH2) were used to covalently functionalize graphene with graphene content of 5.0 wt%. Results showed that lambda(z) was enhanced with the chain length of NH2-PEG-NH2 increased, but lambda(x) reached a maximum value at a certain chain length of NH2-PEG-NH2. The maximum lambda(z) and lambda(x) of GA are 0.406 W m(-1) K-1 and 9.710 W m(-1) K-1, respectively. This study serves as a foundation for further research on the thermal conductive property of graphene nanocomposites using different chain lengths of polymer modifier to improve the lambda(z) and lambda(x) of the thermal conductive materials.
