Elastic and conductive MWCNT/SBS nanocomposites as superior piezoresistive sensors

Abstract

Herein conductive elastomers by homogeneous distribution of multi-walled carbon nanotubes (MWCNTs) in a styrene-co-butadiene-costyrene (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.

Wearable Electrochemical Sensors Based on Nanomaterials for Healthcare Applications

“…Multi-walled carbon nanotubes (CNT) [69][70][71][72][73][74][75][76][77][78][79][80][81] are widely used in sensor applications and can be uniformly distributed on piezoelectric microspheres. Based on the flexible strain sensor of three-dimensional carbon nanotube (CNT) foam-filled nanocomposite, Hao et al [82].…”

Flexible and Transparent Pressure Sensor Based on CNTs Film Microstructure

“…in the form of dopants. [17][18][19][20] For instance, Zhang T et al [21] used polydimethylsiloxane (PDMS) silicone rubber to imitate the microstructure of silk and carbon nanotubes as electrodes in 2014, to obtain a stress-sensor with excellent performance. For example, Li et al [22] used silver nanowires, graphene and polyamide nanofibers to form a flexible pressure-sensor.…”
