Highly Stretchable Supercapacitors Enabled by Interwoven CNTs Partially Embedded in PDMS

We present flexible and stretchable supercapacitors composed of interwoven carbon nanotubes (CNTs) embedded in polydimethylsiloxane (PDMS) substrates. CNTs are grown using atmospheric-pressure chemical vapor deposition (APCVD) on a Si/SiO2 substrate and then partially embedded into PDMS. This unique process permits a rapid and facile integration of the interwoven CNT–PDMS structure as a flexible and stretchable supercapacitor electrode with a...
