Abstract: Using hydrogenated dimer acid,1,6-hexamethylenediamine,polyether amine D-230 and caprolactam as raw materials,the graphene oxide-enriched hydrogenated dimer acid-based nylon compolymer was synthesized by in situ polymerization.The results showed that the tensile strength was 51.3MPa,the elongation at break was 457.3%,the flexural strength was 36.3MPa and the absorption energy of notched impact strength was 84kJ/m2,when the content of graphene oxide in the nylon matrix was 0.08%.Thermogravimetric analysis and differential thermal analysis showed that the decomposition temperature of nylon and the final residual carbon content were also improved.From the observation of modified nylon by scanning electron microscopy,it can be seen that the graphene oxide was uniformly dispersed in the nylon.The enhanced effecst of oxidized graphene were obvious and the properties of prepared copolymerized nylon were more than those of common nylon.
