NOVELTY - Preparing linear low density polyethylene composite comprises mixing graphene and carbon nanotube to form carbon nano-particles, and melt mixing the carbon nano-particles with linear low density polyethylene. USE - The method is useful for preparing a linear low density polyethylene composite, which is useful for a fiber, a film, a plastic product (all claimed) such as pipe, container, toy, plastic bag, wire cover and membrane. ADVANTAGE - The prepared composite has excellent tensile strength, impact strength, electric resistance, heat resistance and mechanical property, and is inexpensive.
