NOVELTY - The preparation method of polyamide 6 composite material involves dissolving graphene oxide powder in mixed solution and then mixing, adding modified sericite to the mixture in a mass ratio of 1:(1-25) and then processing for 2-4 hours, adding caprolactam to the mixture in a mass ratio of 1:(10-200) and then reacting, polymerizing the mixture and then slicing, extracting the mixture and drying. USE - The method is useful for preparation of polyamide 6 composite material, which is useful for preparation of high strength and low elongation polyamide fiber. ADVANTAGE - The method enables preparation of polyamide 6 composite material with excellent mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for polyamide 6 composite material prepared by the method.
