CONDUCTIVE POLYMER MATERIAL, USE OF SAME, AND A METHOD FOR THE PRODUCTION OF SAME

摘要

The invention relates to a conductive elastomer provided and formed from a base elastomer and conductive solid particles that are distributed therein. The conductive particles used are: a) platelet-shaped conductive particles and/or b) dendritic conductive particles and/or c) other elongated conductive particles with a length:width ratio of greater than or equal to two. It has been seen that a combination of ball-shaped and platelet-shaped conductive particles is particularly advantageous. The particles can additionally be aligned by the pouring, application using a doctor blade, or drawing of the dissolved or not-yet cured mixture. The polymer is particularly suitable for medical electrodes for capturing and emitting signals. The material rennulus elastic, and conductive when stretched or bent.
