Electrical Properties of Composite Materials with Electric Field-Assisted Alignment of Nanocarbon Fillers

The article reports about electric field-induced alignment of the carbon nanoparticles embedded in epoxy matrix. Optical microscopy was performed to consider the effect of the electric field magnitude and configuration, filler morphology, and aspect ratio on alignment process. Characteristic time of aligned network formation was compared with modeling predictions. Carbon nanotube and graphite n...

Influence of Ultraviolet/Ozonolysis Treatment of Nanocarbon Filler on the Electrical Resistivity of Epoxy Composites

In the present work, we have investigated concentration and temperature dependences of electrical conductivity of graphite nanoplatelets/epoxy resin composites. The content of nanocarbon filler is varied from 0.01 to 0.05 volume fraction. Before incorporation into the epoxy resin, the graphite nanoplatelets were subjected to ultraviolet ozone treatment at 20-min ultraviolet exposure. The electr...

The electrical properties of polymer nanocomposites with carbon nanotube fillers.

The electrical properties of polymer nanocomposites containing a small amount of carbon nanotube (CNT) are remarkably superior to those of conventional electronic composites. Based on three-dimensional (3D) statistical percolation and 3D resistor network modeling, the electrical properties of CNT nanocomposites, at and after percolation, were successfully predicted in this work. The numerical a...

The inversion is the Non-Linear Conjugate Gradient (NLCG) algorithm of Rodi and Mackie (2001). This seeks to efficiently find a model that minimizes the objective function) P(τ χ S 2 m + = where ∑ = = N 1 i 2 i 2 i 2 σ r χ is the sum of the squared data residuals weighted by their variances and P(m) is a structure penalty function. At each choice of trade-off parameter τ, the resulting model m ...
