研究了多壁碳纳米管 (MWNTs)薄膜的湿敏特性 ,实验所用的多壁碳纳米管是用热灯丝化学气相沉积法 (CVD)合成的 .分别对未修饰和修饰的多壁碳纳米管膜温度和湿度特性进行研究后发现 ,修饰的多壁碳纳米管对温度和湿度非常敏感 ,且对湿度的响应时间和恢复时间短 ,重复性好 .而未修饰的多壁碳纳米管对温度和湿度不太敏感 .对修饰多壁碳纳米管的湿敏特性进行了理论分析 ,给出了其理论表示式
The wet-sensitive properties of multi-walled carbon nanotubes (MWNTs) films were investigated. Multi-walled carbon nanotubes (MWCNTs) were synthesized by thermal filament chemical vapor deposition (CVD) The results showed that the modified multi-walled carbon nanotubes (CNTs) were very sensitive to temperature and humidity, and had short response time and recovery time to humidity with good repeatability.The unmodified multi-walled carbon nanotubes (CNTs) And humidity is not sensitive.Modified multi-walled carbon nanotubes moisture-sensitive properties of a theoretical analysis, given its theoretical expression
