Mechanisms of Single-Walled Carbon Nanotube Network Formation and Its Configuration in Polymer-Based Nanocomposites

The reinforcing and conductive performance of carbon nanotube polymer-based nanocomposites depends on the established network its configuration. Within this study, we report underlying mechanisms such formation utilizing single-walled nanotubes (SWCNTs) in low- high-density polyethylene matrices. Mechanisms were theoretically evaluated through Doi–Edwards theory experimentally confirmed plasma etching coupled with electron microscopy as well rheological flow tests. Results showed that is constructed from SWCNT bundles, which geometrically entangle at a critical volume fraction ?v,crit (number rods: ? ? 30). Below ?v,crit, bundles behave individual units may align direction. Above rotation constrained by neighboring units, leading to random Moreover, successfully explains bundle behavior Brownian entity predicts diminishing thermo- hydro-dynamically driven diffusion, can be manipulated during production enhance reinforcing/conductive functionality materials.
