摘要：

The novel graphene non-covalently functionalized with amino-terminated dendronized polyamide (DPA) was prepared, then reduced and filled into the PA6 to prepare a series of nanocomposites. The structures and thermal properties of products were investigated by FTIR, XPS, XRD, TEM, SEM, TG, thermal conductivity measurements. The results revealed that mediated by the DPA, the amino-terminated dendronized polyamide functionalized graphene nanosheets (DPA-GNs) show good solubility in the organic solvents and more compatible with organic polymer matrix, which results in a certain promotion in thermal stability and thermal conductivity of nanocomposites.
