Electrically Conductive Polymer Nanocomposites

ABSTRACTNew unique abilities towards solvents' vapor of electrically Conductive Polymer nanoComposites (CPCs) have made it a subject, holding the attention of research groups. The direct conversion from chemical information into an electrical signal can take advantage of existing low power microelectronics and sensing technology such as detection of toxic vapor; environmental monitoring in chemical industry and quality control in food processing, beverage and perfume industry. Conductive Polymer nanoComposite (CPC) is a heterogeneous system consisting of insulated polymer matrices and conductive nanofillers. In this paper we have investigated a new route for CNT grafting via ring opening polymerization of e-caprolactone. The influence of this treatment on chemo-electrical properties of the so-called CPC based sensor was investigated in this work.

Carbon nanoparticles possess a combination of high electrical and thermal transport properties, as well as low density and different morphologies that make them a good choice to reinforce plastics. Polymer nanocomposites offer great expectations for new and unexpected applications due to the possibility of changing their electrical/thermal behavior by adding nanoparticles while retaining the flexibility and processability of plastics. The possibility of electrical and thermal conduction in a polymer matrix with low amounts of nanoparticles brings opportunity for high demanding applications such as electrical conductors, heat exchangers, sensors, and actuators. Polyolefin nanocomposites offer a significant challenge due to their insulative nature and low affinity for carbon nanoparticles; due to the latter, new production tendencies are proposed and investigated.
