A Route for Polymer Nanocomposites with Engineered Electrical Conductivity and Percolation Threshold

Polymer nanocomposites with engineered electrical properties can be made by tuning the fabrication method, processing conditions and filler’s geometric and physical properties. This work focuses on investigating the effect of filler’s geometry (aspect ratio and shape), intrinsic electrical conductivity, alignment and dispersion within the polymer, and polymer crystallinity, on the percolation t...

Conductive Copper-PMMA Nanocomposites: Microstructure, Electrical Behavior, and Percolation Threshold as a Function of Metal Filler Concentration

The copper-PMMA conductive composites were manufactured using different copper concentrations dispersed into the polymeric matrix by hot compression molding in inert atmosphere. The PMMA matrix was analyzed using dilute solution viscosimetry analysis and it did not evidence degradation in its molecular weight. The microstructure was examined by means of SEM and the electric conductivity was mea...

Determination of the electrical percolation threshold of Polystyrene-Graphene Oxide nanocomposite using the experiment and simulation methods
