Conductive polyester composition

A conductive polyester composition, comprising:

• a polyester base material;
• and
• a conductive reinforcing material, wherein the conductive reinforcing material includes a plurality of carbon nanotubes, and the plurality of carbon nanotubes are dispersed in the polyester base material;
• wherein in each of the carbon nanotubes, a length of the carbon nanotube is defined as L, a diameter of the carbon nanotube is defined as D and is between 1 nanometer and 30 nanometers, and an L/D value of the carb on nanotube is between 1,000 and 2,000;
• wherein the plurality of carbon nanotubes are in contact with each other to form a plurality of contact points, so that the conductive polyester composition has a surface impedance of not greater than 107 Ω/sq;
• a compatibilizer configured to assist in dispersing the plurality of carbon nanotubes in the polyester base material, wherein, based on a total weight of the conductive polyester composition, a content of the compatibilizer is between 1.5 wt% and 10 wt%,
• wherein the plurality of carbon nanotubes of the conductive reinforcing material are at least one material selected from a group consisting of hydroxylated carbon nanotubes and carboxylic carbon nanotubes;
• wherein the compatibilizer is a polyolefin compatibilizer formed by grafting, modification or copolymerization of glycidyl methacrylate (GMA), or a siloxane compound.
