Abstract
Characterization of electron beam cross-linked ethylene–octene copolymer composites with carbon nanotubes
Highlights
The effect of radiation cross-linking on the properties of Engage® 8200 ethylene–octene copolymer (EOC) with multiwalled carbon nanotube (CNT) nanocomposites was evaluated
In order to achieve good CNT dispersion in the EOC matrix, an ultrasound assisted procedure was used to prepare masterbatches followed by thermoplastic mixing to make the final EOC/CNT composites with a wide ratio of CNT filler concentrations
The gel content for EOC 8200 reported by Svoboda et al reached 80% already at 60 kGy dose due to the more effective re-circulated flux of accelerated electrons generated by the toroidal linear accelerator of 10 MeV energy [18]
Summary
The effect of radiation cross-linking on the properties of Engage® 8200 ethylene–octene copolymer (EOC) with multiwalled carbon nanotube (CNT) nanocomposites was evaluated. Much interest has been applied to carbon nanofiller reinforced Engage trademark (Dow) ethylene– octene copolymers (EOCs), made by selective catalysts causing regular distribution of 1-octene comonomers, and leading to good dispersion of CNTs in their matrices of thermoplastic elastomer behaviour [10]. Such composites have shown applications in gas and vapour separation [11] as well as force sensors due to conductive pathways in elastic matrices depending on their comonomer content [12,13].
