Conductive polymer foams with carbon nanofillers – Modeling percolation behavior

Development and Modeling of Thermally Conductive Polymer/Carbon Composites

Connectivity percolation of polydisperse anisotropic nanofillers.

We present a generalized connectedness percolation theory reduced to a compact form for a large class of anisotropic particle mixtures with variable degrees of connectivity. Even though allowing for an infinite number of components, we derive a compact yet exact expression for the mean cluster size of connected particles. We apply our theory to rodlike particles taken as a model for carbon nano...

Thermal Conductivity of Polymer Composites Filled with Nanofillers

Polymer nanocomposites are composed of polymer materials reinforced with nano fillers.In the present study the effective thermal conductivity of the composites filled with nanofillers has been investigated using commercially available finite element software ABAQUS 6.11. The nanofillers used were alumina particles and multi-walled carbon nanotubes (MWNTs) and the matrix was considered to be mad...

Polymer Nanocomposites—A Comparison between Carbon Nanotubes, Graphene, and Clay as Nanofillers

Nanofilled polymeric matrices have demonstrated remarkable mechanical, electrical, and thermal properties. In this article we review the processing of carbon nanotube, graphene, and clay montmorillonite platelet as potential nanofillers to form nanocomposites. The various functionalization techniques of modifying the nanofillers to enable interaction with polymers are summarized. The importance...

Modeling and Data Analysis of Conductive Polymer Composite Sensors

MODELING AND DATA ANALYSIS OF CONDUCTIVE POLYMER COMPOSITE SENSORS Hua Lei Department of Chemical Engineering Doctor of Philosophy Conductive polymer composite sensors have shown great potential in identifying gaseous analytes. To more thoroughly understand the physical and chemical mechanism of this type of sensors, a model was developed by combining two sub-models: a conductivity model and a ...
