Abstract The preparation and characterization of zinc oxide nanorods on flexible bio-based carbon nanotubes cotton (CNTC) was investigated. CNTC was synthesized via floating catalyst chemical vapor deposition reactor using waste cooking palm oil as hydrocarbon source. One sided CNTC facet was used as substrate hosting the growth of zinc oxide nanorods. The zinc oxide (ZnO) nucleation seed layer was deposited onto the CNTC using 99.9% Zn target and ZnO nanorods were synthesized via chemical bath deposition method. It was observed that the average diameter and length of nanorods increased proportionally to the increase of seed layer thickness. However, the aspect ratio decreased with the escalation of seed layer thickness due to its diameter significant enlargement. The highest aspect ratio is 9.4 and the lowest is 6.3 for seed layer thickness at 117 nm and 282 nm respectively. The electrical conductivity measurement showed that sample with thicker seed layer yielded better conductive value due to the ease of electrical charges movement with lower energy gap. Conclusively, ZnO nanorods have been successfully grown on CNTC surface via facile synthesis route with minimal sample pre-preparation exertion. The hybrid of ZnO/CNTC offers promising future as CNTC is flexible, readily available and incurs lower cost than other substrates.

化学浴沉积法氧化锌成核对柔性生物基碳纳米管棉的影响

摘要 研究了在柔性生物基碳纳米管棉（CNTC）上制备和表征氧化锌纳米棒。以废弃食用棕榈油为烃源，通过漂浮催化剂化学气相沉积反应器合成CNTC。一侧的CNTC小面用作承载氧化锌纳米棒生长的基底。使用 99.9% Zn 靶将氧化锌 (ZnO) 成核种子层沉积到 CNTC 上，并通过化学浴沉积法合成 ZnO 纳米棒。观察到纳米棒的平均直径和长度与种子层厚度的增加成比例地增加。然而，由于其直径显着增大，纵横比随着种子层厚度的增加而降低。最高纵横比为 9.4，最低为 6。3 分别为 117 nm 和 282 nm 的种子层厚度。电导率测量表明，由于电荷移动容易且能隙较低，具有较厚种子层的样品产生更好的导电值。最终，ZnO 纳米棒已通过简便的合成途径成功地在 CNTC 表面生长，并且样品预制备工作量最少。ZnO/CNTC 的混合体提供了充满希望的未来，因为 CNTC 具有灵活性、易于获得且成本低于其他基材。ZnO 纳米棒已通过简便的合成途径成功地在 CNTC 表面生长，并且样品预制备工作量最少。ZnO/CNTC 的混合体提供了充满希望的未来，因为 CNTC 具有灵活性、易于获得且成本低于其他基材。ZnO 纳米棒已通过简便的合成途径成功地在 CNTC 表面生长，并且样品预制备工作量最少。ZnO/CNTC 的混合体提供了充满希望的未来，因为 CNTC 具有灵活性、易于获得且成本低于其他基材。
