▎ 摘　　要

NOVELTY - Graphene composite modified high-strength polyethylene fibers comprise 98-99.8 wt.% ultra-high-molecular-weight polyethylene and 0.2-2 wt.% graphene composition. The ultra-high-molecular-weight polyethylene has molecular weight of 2400000-2600000. The graphene has particle diameter of 0.5-1.5 mu m and particle size of 0.33-0.35 nm. USE - Graphene composite modified high-strength polyethylene fibers (claimed). ADVANTAGE - The graphene composite modified polyethylene fibers having excellent strength are prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene composite modified high-strength polyethylene fibers.
