Popis: Sensor technology is significant to monitor organic contaminations on water for the present industries. In this letter, highly sensitive carbon nanotube (CNT) based silicone rubber composites (CNTRs) are used as the candidate for sensing materials, which yet display unstable liquid sensing outputs owing to poor dispersion of CNTs. As hybrid carbon blacks (CBs) are added, CNT/CB composites are prepared to solve bad distribution of CNTs. CNT/CB composites achieve a better conductivity, larger sensing capacity and more stable sensing response on singular chemical liquids than CNTR. Importantly, growing resistance responsivities are discovered as CNT/CB composites circularly contact toluene and water. We therefore design the sensing application to monitor toluene suspensions on water.
