| 摘要 | PURPOSE: To improve the oxidation resistance, mechanical strength and flexibility of an electric conductor by doping an insoluble and infusible basic body, obtained through the process of heat-treating a polycarbodiimide resin, with an electron-donative doping agent or an electron-acceptable doping agent. CONSTITUTION: A polycarbodiimide resin can be manufactured through a process of condensation reaction involving decarbonation of an organic diisocyanate. An electron-donative doping agent is selected from the First Group A metal including lithium, sodium, potassium, rubidium and cesium, and an electron- acceptive doping agent on the other hand is selected from anions selected from such materials as fluorine, chlorine, bromine, a halogen of iodine, halides of As, F 5 , PF 5 , BF 5 , BC1 3 , BBr 2 and the like, the oxides of such uon-metallic elements as SO 3 , N 2 O 3 and the like or the inorganic acids of H 2 SO 4 , HNO 3 , HC1O 4 and the like. Thus, an electric conductor can be obtained with excellence in oxidation resistance, mechanical strength and flexibility. COPYRIGHT: (C)1991,JPO&Japio |
