ELECTROCONDUCTIVE ADHESIVES BASED ON POLYURETHANE WITH MULTIWALLED CARBON NANOTUBES

Abstract

In the present study, we prepared and characterized electrically conductive adhesives based on polyurethane filled with two kinds of multiwalled carbon nanotubes (MWCNTs), viz. pristine MWCNTs and acid treated MWCNTs, respectively. The influence of the type of filler on the dispersibility within the polyurethane matrix and the corresponding electrical conductivity is investigated. The electrical conductivity of the prepared specimens was measured using a four-point probe. The morphology and dispersibility of the fillers were observed by field emission scanning electron microscopy and transmission electron microscopy.
