Electric field alignment of multi-walled carbon nanotubes through curing of an epoxy matrix

The electrical alignment of multi-walled carbon nanotubes (MWCNT) in an epoxy resin was studied through curing using electrical measurements and optical microscopy. The epoxy system was composed by diglycidyl ether of bisphenol-A and 4,4'-methylene bis-(3-chloro 2,6-diethylaniline). Long multi-...
