Herein conductive elastomers by homogeneous distribution of multi‐walled carbon nanotubes (MWCNTs) in a styrene‐ co ‐butadiene‐ co ‐styrene (SBS) triblock copolymer matrix is reported. The inherent π–π stacking ensures nearly single‐layer adsorption of the SBS molecules on the surfaces of MWCNTs, translating into reliable interfacial interactions. The resulting MWCNT/SBS nanocomposites are highly elastic and conductive. It is believed that this finding opens up a new way to fabricate conductive elastomers holding great promise as superior piezoresistive sensors that may integrate a ‘touch’ function in wearable electronics and computers.
