| 摘 要： | 为降低WO3气敏元件的工作电压,改善WO3基敏感材料的气敏性能,采用化学吸附沉淀-水热法合成WO3和WO3/SWCNT复合材料,并研究矿化剂用量和SWCNT掺杂量对其气敏性能的影响.结果表明,大剂量矿化剂的使用会降低WO3的气敏性能；碳纳米管掺杂可以使WO3在较低的工作温度下有较高的灵敏度.SWCNT掺杂量为1％的元件...

| Abstract: | To reduce the working voltage and enhance the sensitivity of the sensors based on WO3,WO3 and WO3/SWCNT nanocomposites were prepared through chemical adsorption precipitation-hydrothermal method.The effect of the additive amounts of mineralizer and the doping amounts of SWCNT to the gas sensing characteristics of the gas sensors based on the as-synthesized WO3 and WO3/SWCNT nanocomposites were studied.The results showed that much amount of mineralizer mook the sensitivity of WO3 was reduced,and the SWCNT do... |
