| Résumé : |
The aim of the study is to investigate the conductivity and heat generation of a compound consisting of 90 wt%, polyethylene (PE) and 10 wto/o carbon black (CB). At this ratio the percolation barrier is exceeded. The produced filaments are highly conductive for polymers with a conductivity of 10 S/m to a = 50 S/m. Compared to pure polymer, which is rather an electric insulator (a = 10-5 S/m to a = 10-12 S/m ), this is a quite good property ; compared to iron or copper in the range of ? = 107 S/m further improvement is needed to have a fully conductive polymer. Indeed, this semiconductive property is the reason vvhy this compound is suitable of fiber-based heating. The electric tosses are used for heat generation. By varying the production process parameters, the influence of different variables is analyzed and the desired properties are optimized. So far, compound produced at the ITA had conductivities in the single-digit S/m area. The improvement by a factor of 10 is further described in the paper. |
