Claim 0:
1. A conductive concentrated resin composition, comprising:
(a) 100 parts by weight of a base resin comprising 50% to 95% by weight of a first polyamide resin, 2.5% to 20% by weight of a first polar polymer, and 2.5% to 30% by weight of a first non-polar polymer based on a total weight of the base resin;
(b) 10 parts to 40 parts by weight of a carbon nanofibril;
(c) 0.5 parts to 5 parts by weight of a carbon nanoplate; and
(d) 0.5 parts to 4 parts by weight of a nanosilicate,
based on 100 parts by weight of the base resin,
wherein the first polyamide resin is one or more selected from the group consisting of polyamide 6, polyamide 66, polyamide 46, polyamide 11, polyamide 12, polyamide 610, polyamide 612, polyamide 6/66, polyamide 6/612, polyamide MXD6, polyamide 6/MXD6, polyamide 66/MXD6, polyamide 6T, polyamide 6I, polyamide 6/6T, polyamide 6/6I, polyamide 66/6T, polyamide 66/6I, polyamide 6/6T/6I, polyamide 66/6T/6I, polyamide 9T, polyamide 9I, polyamide 6/9T, polyamide 6/9I, polyamide 66/9T, polyamide 6/12/9T, polyamide 66/12/9T, polyamide 6/12/9I, and polyamide 66/12/6I,
wherein the first polar polymer is an ethylene-α-olefin copolymer modified with at least one of α,β-unsaturated dicarboxylic acid and anhydrides thereof, wherein the α-olefin included in the first polar polymer has 3 to 10 carbon atoms, wherein the first polar polymer is a graft polymer of the at least one of α,β-unsaturated dicarboxylic acid and anhydrides thereof with an ethylene-α-olefin copolymer backbone or a copolymer of the at least one of α,β-unsaturated dicarboxylic acid and anhydrides thereof, the ethylene and the α-olefin, and
wherein the first non-polar polymer is an ethylene-α-olefin copolymer having no polar group, wherein the α-olefin included in the first non-polar polymer has 3 to 10 carbon atoms.
