Preparation and Characterization of Electrically Conductive Polymer Nanocomposites with Different Carbon Nanoparticles

Abstract

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.

Fabrication of “electroactive cells” using bio-inspired polydopamine-derived carbon nanoparticles for manipulation of cells with electrical stimulation

“…As for the endowed conductivity of CNPs, carbon nanomaterials are known to have excellent electrical conductivity and therefore have been utilized in some solar cells, coatings of microelectrodes, transparent conductive films, electrochemical sensors, and so on. However, we found only a few publications discussing the electrical conductivity of carbon nanoparticles in biomedical applications, compared to 2D graphene nanoparticles and 1D carbon nanotubes (Campuzano, Yáñez-Sedeño and Pingarrón, 2019;Cruz-Delgado et al, 2021). Most research is focused on carbon nanotubes and graphene nanoparticles with excellent electrical conductivity, which always suffer from the dispersion issue, especially in a matrix or an aqueous solution, yet the CNPs synthesized or dehydrated in the solution state can be easily dispersed in an aqueous solution.…”
