详细解释:
In air atomsphere , the CNT films have the most sensitivity to water vapour, while they are not sensitive to CO2、CH4、O2. The biggest change of resistance of CNT films is about 18% between dry air and air of 48% humidity. 空气中,碳纳米管膜对水分子最敏感,而对CO_2、CH_4、O_2等不太灵敏。 在干燥空气和湿敏为48%的空气中,碳纳米管膜的电阻变化约为18%。
