Title:
導電性ポリマーを含有する電気デバイス
Document Type and Number:
Japanese Patent JP3605115
Kind Code:
B2
Abstract:
The use for an electrical device (1) of an element (7) composed of a conductive polymer is positioned in contact with the surface layer of one or more metal electrodes (3, 5). The metal electrode contains a base layer (9) which comprises a first metal, an intermediate metal layer (15) which comprises a metal that is different from the first metal, and a surface layer (17) which (i) comprises a second metal, (ii) has a centre line average roughness Ra of at least 1.3, and (iii) has a reflection density Rd of at least 0.60. The conductive polymer composition preferably exhibits PTC behaviour. The electrical devices, which may be, for example, circuit protection devices or heaters, have improved thermal and electrical performance over devices compared with electrodes which do not meet the centre line average roughness and reflection density requirements.
