Electric fields for the tailoring of polymeric nonocomposites with carbonaceous filler particles
GEM PPM INSA cle Lyon, Villeurbanne
We report on the application of electric fields for the alignment and network formation of carbonaceous fillers in an epoxy resin thermoset during the curing. The structuring of the conductivity distribution by means of inhomogeneous electric fields in a carbon black filled epoxy resin will be shown. The use of homogeneous electric fields induces a preferential orientation and chain formation of fibrous filler particles. This will be demonstrated for dispersions of carbon nanofibres in epoxy resin in an alternating electric field. The resultant anisotropy of the electrical properties will be discussed.
