▎ 摘  要

NOVELTY - A polyester-based and conductive master batch-based carbon nanotube and graphene compounding system comprises 85-98 wt.% polyester, 0.2-2 wt.% carbon nanotubes, 1-8 wt.% graphene and 0.5-5 wt.% compatibilizer. The compatibilizer is selected from aromatic vinyl monomer, acrylonitrile-based monomer and terpolymer copolymerized with glycidyl (meth)acrylate. USE - Polyester-based and conductive master batch-based carbon nanotube and graphene compounding system used for preparing conductive material for injection molding, extrusion and modification applications. ADVANTAGE - The polyester-based and conductive master batch-based carbon nanotube and graphene compounding system provides conductive material with excellent electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polyester-based and conductive master batch-based carbon nanotube and graphene compounding system, which involves (1) dispersing carbon nanotubes and graphene in an inert volatile solvent, stirring at room temperature for 10-30 minutes to obtain carbon nanotube suspension and graphene suspension, (2) ultrasonically treating the carbon nanotube suspension and graphene suspension at 400-800 W for 1 hour to obtain carbon nanotube dispersion and graphene dispersion, (3) mixing carbon nanotube dispersion, graphene dispersion and polyester, stirring at 1300-2000 rpm to obtain dispersion material, (4) mixing the dispersion material and compatibilizer, adopting twin-screw melt extrusion process at 190-280 degrees C and 100-400 rpm to obtain final product.
