油田集成电路管的制备及性能研究

Research on Preparation and Performance of Oilfield Integrated Circuit Tube

在NH4F体系和HF体系中制备了油田集成电路碳纳米管,研究了阳极氧化电压和氧化时间对碳纳米管生长、形貌和光催化性能的影响,并分析了其作用机理。结果表明,NH4F体系中,随着氧化电压的升高,形成的碳纳米管的管长不断增大,排列也更加致密,生长方向逐渐从部分垂直于基底转化为全部垂直于基底;HF体系中,三种氧化电压下的纳米管都较为细密,没有出现类似的竹节结构,相同氧化时间下的纳米管也更长;无论是NH4F体系还是HF体系,氧化电压为30V时制备的纳米管具有最佳的光催化性能。

Integrated circuit titanium nanotubes was prepared in NH4F and HF systems, the effect of anodic oxidation voltage and oxidation time on the carbon nanotube growth, morphology and photocatalytic properties was studied,and the mechanism was analyzed. The results showed that, in NH4F system, with the increase of oxidation voltage, the length of the carbon nanotubes increased, and arranged more compact, the growth direction gradually from partly vertically on the substrate into all perpendicular to the substrate;in HF system, the nanotubes were all fine under three oxidation voltage,and had no similar bamboo structure, the nanotubes were relatively longer under the same oxidation time;in both NH4F system and HF system, nanotubes had the best photocatalytic performance when the oxidation voltage was 30 V.
