Transparent elongation and compressive strain sensors based on aligned carbon nanowalls embedded in polyurethane
Original language description
Highly extensible transparent composite materials comprised of maze-like vertically aligned carbonnanowalls embedded perpendicularly into a polyurethane film were used as strain tensors and testedby an electrical resistance method in the course of extension, extension/relaxation and compres-sion/expansion cycles. The maze-like carbon nanowall networks with wall-to-wall average distancesof 100, 200 and 300 nm were formed on SiO2-coated Si substrates by a plasma-enhanced chemical vapordeposition system. Afterwards, the nanowall network was embedded into a stretchable polyurethanematrix which enabled a high deformation of the composite. The measured extensibility of the compos-ite was over 440 %, and its resistance increased with the extension. The sensitivity of the detection ofextension, which was evaluated by the gauge factor, increased over 2000. These sensor properties can bereadily tuned by varying distances of nanowalls within the network. Finally, thanks to their optical trans-parency in the visible light region and thermoelectric properties, these composites offer a wide range offurther practical applications.
