Název v původním jazyce

Electromagnetic shielding of epoxy resin composites containing carbon fibres coated with polyaniline base.

Popis výsledku v původním jazyce

Polymers filled with carbon fibers have recently received attention due to their remarkable conducting and dielectric properties. The fibrous character of the filler causes that the percolation threshold of these systems is reached at 1-2 vol. % of conducting component. The present study has been aimed at electromagnetic interference shielding properties of epoxy resin composites containing short carbon fibers coated with a layer of non-conducting polyaniline base. Due to the coating, the percolation threshold shifted to 16-20 vol. % of the filler. The composites of short carbon fibers coated with nonconducting polyaniline base show a high AC conductivity in high frequencies (10 MHz -1300 MHz) and low DC conductivity at the same time. They can thus beused for transmitting high-frequency signals, and for shielding of low-frequency ones. Moreover, they do not short circuit the surface of electronic systems.
