Abstract
Abstract Stretchable conductors of multi-walled carbon nanotubes (MWCNTs) filled thermoplastic vulcanizate (TPV) based on polypropylene(PP)/ethylene-propylene -diene rubber (EPDM) blends were fabricated via a simple melt compounding method. MWCNT particles could be selectively distributed in PP matrix induced by the dynamic vulcanization reaction occurred firstly. And the dispersion state of MWCNTs can be improved via increasing the constituent ratio of PP and EPDM. TPV composites with a constituent ratio of 50: 50 wt% exhibits a tiny increase of gauge factor (GF) even up to 100% strain loading, showing a good potential to be used as highly stretchable conductors. Meanwhile, comparing with thermoplastic elastomer (TPE) composites fabricated by the same processing, these TPVs exhibits a lower percolation threshold, enhanced electromagnetic interference (EMI) performance and balanced mechanical performance. Thus, this work provides a simple and scalable melt compounding approach to fabricate highly stretchable conductors with high EMI shielding.
