Poly(ionic liquid)-wrapped single-walled carbon nanotubes for sub-ppb detection of CO2.
An ultrasensitive CO(2) sensor with a detection limit of 500 ppt was achieved using poly(ionic liquid)-wrapped single-walled carbon nanotubes as sensing materials. The sensor exhibited superior selectivity to CO(2) and was resistant to the interference of relative humidity.
