Although the characteristics of multi-walled carbon nanotube (MWCNT)-incorporated polymer composites have been studied in various aspects for several decades, the thickness and length of MWCNT applied to each research are different, limiting the fundamental understanding of the characteristics and mechanism of composites. In this study, we systematically investigated the effect of morphology based on the difference in MWCNT length on the composite properties via measuring mechanical, thermal and electrical properties. As a result of FE-SEM and micro-CT, short MWCNT was more uniformly dispersed in polyamide 6 (PA6) polymer matrix than long one, which was accordingly correlated with thermal conductivity, electrical conductivity and tensile performance of composite. We hope these fundamental understanding will be applied as a design rule for the morphological selection of MWCNT for a wide range of application.
