| 摘要 |
The invention relates to conductive elements and their preparation. The novel elements comprise a support (preferably a flexible polymeric film support) and randomly distributed fibres (e.g. glass fibres) which are partially embedded in the support. Solid electrically conductive particles are adherent to the protruding portions of the fibres, forming a conductive layer. Such elements are prepared by applying a dispersion of conductive particles (preferably an aqueous dispersion of carbon particles) to a substrate comprising a support and random fibres partially embedded in the support and partially protruding therefrom, followed by solidifying the dispersion. The elements are particularly useful as heaters. |
