Abstract

This article reports a solvent-free, ultrasoft and conductive PDMS bottlebrush elastomer (BBE) composite with single-wall carbon nanotubes (SWCNTs) as conductive fillers. The conductive SWCNT/BBE with a filler concentration of 0.4–0.6 wt% reveals an ultralow Young’s modulus (<11 kPa) and satisfactory conductivity (>2 S/m) as well as adhesion property. Ultrasoft electronics based on laser cutting and 3D printing of conductive and non-conductive BBEs are fabricated and demonstrated for wearable sensing, soft robotics, and electrophysiological recording.
