Multi‐walled carbon nanotubes (MWCNTs) were melt‐mixed with the liquid crystalline polymer (LCP) phase to investigate MWCNTs dispersion and the electrical conductivity of LCP/MWCNTs composite. LCP/MWCNTs composite showed an insulating behavior even at 5 wt% of MWCNTs concentration, wherein MWCNTs were dispersed as ‘individualized’ as well as ‘nano‐agglomerated’ state in the LCP matrix. Further, LCP along with MWCNTs were melt‐mixed with 50/50 (wt/wt) polyamide 6 (PA6)/ acrylonitrile butadiene styrene copolymer (ABS) and 50/50 (wt/wt) polyamide 66 (PA66)/ABS blends. Morphological observations showed that MWCNTs were preferentially dispersed in the polyamide (PA) phase, which led to the refinement of the ‘co‐continuous’ morphology. The electrical conductivity results showed that the theoretical electrical percolation thresholds of 0.9, 1.1 and 1.5 wt% of MWCNTs were achieved in the corresponding 90/10 (PA6/ABS)/LCP+MWCNTs, 95/5 (PA6/ABS)/LCP+MWCNTs and 95/5 (PA66/ABS)/LCP+MWCNTs blends. The lower melt‐viscosity associated with the PA phase led to the preferential localization of the MWCNTs in the PA phase. This strategy led to finer network structure of MWCNTs selectively in the PA phase of the ‘co‐continuous’ blend.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
