Electrically conductive polymer resin and method for making same

摘要

Disclosed are polymer resins, including polymer resin sheets, having good electroconductivity and a method for manufacturing the same. The polymer resins exhibit flexibility and show electroconductivity on their surface as well as along their thickness, and thus can be used as electromagnetic wave-shielding materials having impact- and vibration-absorbing properties as well as conductivity.

1. A polymer resin sheet having two major surfaces comprising a polymer component and a conductive filler distributed in the polymer component wherein the polymer component includes at least one first section in which the conductive filler is arrayed in the thickness direction of the polymer resin sheet and at least one second section adjacent to the first section in which the conductive filler is arrayed in the horizontal direction of the polymer resin sheet, wherein the filler forms a conductive network in the polymer resin, the at least one first section providing a sole conductive path from one major surface of the sheet to another major surface of the sheet and the at least one second section providing a sole conductive path along the length and width of the sheet.
