초록
In this study, we investigated a carbon nanotube (CNT) film sensor to detect hazardous and noxious substances distributed in seawater. The response change of the sensor was studied according to environmental temperature, and its temperature coefficient of resistance (TCR, α) was measured. The temperature of the CNT film (~50 µm) was in the range of 20–50oC, and αCNT was calculated to be −0.0011 %/oC. We experimentally confirmed that the CNT film had a smaller TCR value than that of the conventional sensor. Therefore, we investigated the response change of the CNT sensor according to temperature. The CNT sensor showed a relatively small error of approximately 2.3 % up to 30oC, which is within the temperature range of the seawater of the Korean Peninsula. However, when the temperature exceeded 40oC, the error in the CNT sensor increased by more than 5.2 %. We fabricated a metal oxide (ITO, indium-tin-oxide) film and compared its performance with that of the CNT sensor. The ITO sensor showed an error of >12.5 % at 30oC, indicating that in terms of the stability of the sensor to temperature, the CNT film sensor has superior performance.
Abstract
In this study, we investigated a carbon nanotube (CNT) film sensor to detect hazardous and noxious substances distributed in seawater. The response change of the sensor was studied according to environmental temperature, and its temperature coefficient of resistance (TCR, α) was measured. The temperature of the CNT film (~50 µm) was in the range of 20–50oC, and αCNT was calculated to be −0.0011 %/oC. We experimentally confirmed that the CNT film had a smaller TCR value than that of the conventional sensor. Therefore, we investigated the response change of the CNT sensor according to temperature. The CNT sensor showed a relatively small error of approximately 2.3 % up to 30oC, which is within the temperature range of the seawater of the Korean Peninsula. However, when the temperature exceeded 40oC, the error in the CNT sensor increased by more than 5.2 %. We fabricated a metal oxide (ITO, indium-tin-oxide) film and compared its performance with that of the CNT sensor. The ITO sensor showed an error of >12.5 % at 30oC, indicating that in terms of the stability of the sensor to temperature, the CNT film sensor has superior performance.
