One-pot preparation of porous piezoresistive sensor with high strain sensitivity via emulsion-templated polymerization

One-pot preparation of porous piezoresistive sensor with high strain sensitivity via emulsion-templated polymerization
Flexible conductive polymer composite foams (CPCFs) are considered as promising materials for piezoresistive sensors. However, most of them have low strain sensitivity with gauge factor (GF) of around 1.0. Herein, for the first time, W/O emulsion-templated polymerization is developed to fabricate graphene-based flexible CPCFs with high strain sensitivity. Compared to the literature-reported CPCFs, our materials have conductive network with higher specific surface area, improving conductive pathways formation between fillers under compression. In the vicinity of conductive percolation threshold, the CPCF has highest GF of 6.0 within 0–5% strain range and piezoresistive stability, demonstrating its high strain sensitivity and promising applicability in strain sensors.
