The invention discloses a low-creep graphene ultra-high molecular weight polyethylene functional fiber and a preparation method thereof. The low-creep graphene ultra-high molecular weight polyethylene functional fiber is prepared by the following steps: S1, screening graphene oxide nanosheets with the sheet diameter range of 3-4 microns; s2, reacting the screened graphene oxide nanosheets with chiral molecules to obtain modified graphene oxide nanosheets of which the surfaces are grafted with long-chain chiral amino acid molecules; s3, preparing the modified graphene oxide nanosheet and ultra-high molecular weight polyethylene through a dry process to obtain the low-creep graphene ultra-high molecular weight polyethylene functional fiber. According to the preparation method, the graphene oxide nanosheet with the sheet diameter of 3-4 microns is adopted, long-chain chiral amino acid molecules are grafted on the surface of the graphene oxide nanosheet for modification, and the modified graphene oxide nanosheet
