Electrically Conductive Latex-Based Composites

چکیده

Electrically conductive polymer composites filled with carbon black can exhibit the mechanical behavior of a polymer and metallic electrical conductivity. Unfortunately, excessive amounts of carbon black can produce brittle films and too little carbon black can result in low conductivity. Composite conductivity can be dramatically improved by using latex as the matrix starting material. Latex polymers create a segregated network of carbon black during drying, which dramatically reduces the concentration necessary to achieve good conductivity. We have prepared latexes with varying glass transition temperature and particle size to tune both electrical conductivity and mechanical behavior.

Tunneling Conductivity and Piezoresistivity of Composites Containing Randomly Dispersed Conductive Nano-Platelets

In this study, a three-dimensional continuum percolation model was developed based on a Monte Carlo simulation approach to investigate the percolation behavior of an electrically insulating matrix reinforced with conductive nano-platelet fillers. The conductivity behavior of composites rendered conductive by randomly dispersed conductive platelets was modeled by developing a three-dimensional f...

Conformal Pad-Printing Electrically Conductive Composites onto Thermoplastic Hemispheres: Toward Sustainable Fabrication of 3-Cents Volumetric Electrically Small Antennas

Electrically small antennas (ESAs) are becoming one of the key components in the compact wireless devices for telecommunications, defence, and aerospace systems, especially for the spherical one whose geometric layout is more closely approaching Chu's limit, thus yielding significant bandwidth improvements relative to the linear and planar counterparts. Yet broad applications of the volumetric ...
