Graphene has a unique structure and excellent properties. The performance of the polymer can be greatly improved by adding only a small amount of graphene. The crystallographic forms and non-isothermal crystallization kinetics of polyamide 6(PA6)and polyamide 6/Amino graphene(PA6/AG) composite were investigated by X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The results show that
the addition of AG couldn't lead to a distinct change to crystallographic form of PA6.The Avrami equation could successfully discribe the isothermal cryatallization behavior of PA6 and PA6/AG composite.AG in PA6/AG composite could serve as effective heterogeneous nucleating agent
which made the crystallization temperature increased and crystallization rate accelerated.
