Abstract

The invention discloses a graphene / polyolefin elastomer master batch and a graphene antistatic composite material as well as preparation methods thereof. The graphene / polyolefin elastomer master batch is prepared from the following raw materials in parts by weight: 1-100 parts of polyolefin elastomer (POE) or grafted polyolefin elastomer (m-POE), 1-10 parts of graphene and 0.01-1 part of silane coupling agent. The graphene / POE master batch has better electrical property; a polyethylene (PE) antistatic material prepared by adding 1-10% of graphene / POE master batch has the surface resistance less than 1011 omega, so that the use safety of engineering plastics of high-voltage-resistant parts in electrical products can be improved; therefore, the graphene / polyolefin elastomer master batch has remarkable industrial application value.

Description

technical field [0001] The invention belongs to the technical field of graphene / polyolefin conductive composite materials. Specifically, the invention relates to a graphene / polyolefin elastomer masterbatch, a graphene antistatic composite material and a preparation method. Background technique [0002] Since Ruoff et al. reported graphene / polystyrene conductive composites in 2006, researchers at home and abroad have done a lot of research on graphene / polymer nanocomposites. Graphene has a large specific surface area and excellent electrical conductivity. After dispersion, it can form a conductive network in the polymer polymer segment to improve the electrical conductivity of the material; graphene is the thinnest and hardest material known so far. Excellent mechanical properties can improve the toughness and strength of composite materials. Graphene also has extremely excellent thermal conductivity, which has played an important role in improving the multifunctionality of ...
