Electroconductive polyamide resin composition |
摘要 |
There is provided an electroconductive polyamide resin composition comprising: (a) a polyamide resin component obtained from a dicarboxylic acid component comprising oxalic acid and a diamine component comprising a diamine having 4 to 12 carbon atoms, and (b) a fine carbon fiber dispersed in the resin component, wherein a graphite-net plane consisting solely of carbon atoms forms a temple-bell-shaped structural unit comprising closed head-top part and body-part with open lower-end, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a common central axis to form an aggregate, and the aggregates are connected in head-to-tail style with a distance to form the fiber. |

1. An electroconductive polyamide resin composition comprising:
(a) a polyamide resin component obtained from a dicarboxylic acid component comprising oxalic acid and a diamine component comprising a diamine having 4 to 12 carbon atoms, and (b) a fine carbon fiber dispersed in the resin component, wherein a graphite-net plane consisting solely of carbon atoms forms a temple-bell-shaped structural unit comprising closed head-top part and body-part with open lower-end where an angle θ formed by a generatrix of the body-part and a fiber axis is less than 15°, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a common central axis to form an aggregate having an aspect ratio L/D of 2 to 30 wherein D is an outer diameter of the body-part and L is a length of the aggregate, and the aggregates are connected in head-to-tail style with a distance by van der Waals forces to form the fine carbon fiber. |
